COVIDSafe app


I know it’s not right. I feel it’s not right. Just because I lack the vocabulary to argue my point does it mean my position is untenable?

Well, no. But it certainly doesn’t help.

In such situations I find it best to put my head down, move away, and hope that no one notices. A problem arises when my position is challenged and I substitute something else in place of that visceral response which sorta sounds right and, when I say it out loud, sorta feels right, and I drift towards that position. At a fundamental level I think we are all a bit like that. But let’s talk about the COVIDSafe app or, more accurately, the conundrum of “privacy” in a data-driven world.

Life is priceless. That is to say that an individual life lost, be it in measured in days, years, or a lifetime, cannot be brought back by any amount of money. But in a communal sense life has a price. That is to say that society can - and does - put a price on what it is prepared to pay to save a life. In 2015 GiveWell estimated the price to save one life by donating to the Against Malaria Foundation to be USD $3,337.40. In 1985 Ronald Reagan made a deal to sell weapons to Iran in exchange for help freeing 39 US hostages held by Hezbollah in Lebanon while proclaiming he would “never make concessions to terrorists”. QALY (quality-adjusted life year) is a measure of disease burden that allows comparisons of health interventions for different conditions the analysis of which helps determine the cost-effective threshold for a given intervention. At the turn of the century the average cost of prepping and treating a patient with leukaemia in Australia with an allogeneic bone marrow transplant was AUD $250,000 with a survivorship of 60%.

Tomorrow’s world has autonomous vehicles challenged by the trolley problem posed as a real-world dilemma (as opposed to an interesting thought bubble). If there is a choice between striking down an elderly man who has wandered onto the road vs striking 5 children standing on a footpath what action should the autonomous vehicle take? What if the calculations indicate that the elderly man will almost certainly die if struck by the vehicle’s current trajectory but 3 of the 5 children might have moderate injuries but none will die if the car mounts the curb? What if the elderly man standing on the footpath and it is the children who wandered onto the road?

These are tough questions. The general flattening of the COVID-19 pandemic should give us pause to reflect on the social, psychological and economic ramifications of the worldwide response to it.

Let’s be clear that certain institutions full of very smart people exist specifically to ask these questions and provide guidance and answers. Governments can and should act on such advice and thereby implement rules and recommendations. I think it is fair to say that Australia has done well in this regard and the largely bipartisan support in the approach to COVID-19 has been effective.

Now let’s ponder three questions.
Who are at greatest risk of dying from COVID-19?
Who pays for the interventions used to control this disease?
What will change in order to manage this pandemic and mitigate the effect of future pandemics?

Australia is not Italy nor is it the United States. Australia has had a low infection rate for COVID-19 for a number of possible reasons. It is geographically isolated. It was able to learn from the experience of other countries (namely Italy where the disease appeared to start earlier and went like the clappers). It was able to impose a lockdown quickly and effectively. It has a reasonable safety net and a relatively healthy population (I should add a qualifier here: Australia’s indigenous community are mostly rural where infection rates are lower but they remain a high risk group). Australia has a broadly homogenous and competent medical system. And SARS-CoV-2 struck the northern hemisphere in winter while Australians were still enjoying summer.

So what’s next?

The scenario with the old man and the group of children is a common example used for the trolley problem and conveniently provides an analogous solution to the first two questions posed above. In Australia, and generally worldwide, the old and the frail die from the trajectory of COVID-19. The cost of mitigating the natural course of COVID-19 will be borne by the young. Regardless of how clever you want to be about economics there is a cost to pay and this cost rests on the shoulders of future generations. If you think that this can be blown off through fancy financial structures then recognise that the planet we live on is not some inexhaustible asset that can be pillaged without fear of repercussion. The planet is a bountiful resource. But we need to treat it carefully. And we already tested the limits to the point that many - especially young people - felt that things needed to change before anyone knew anything about COVID-19 (think climate change, over-fishing, crop monocultures, pollution etc).

Every life has incalculable value to the individual and to those around them. But just because life is precious does not mean that it cannot be priced. If you choose to take the metric of lives lost from COVID-19 then you must also accept the metrics used to determine the price needed to offset such a loss. QALY is a more nuanced and useful measure but is harder to implement (as is any tool that requires greater granularity in the dataset). It is also political suicide to suggest that a rich, liberal society with a Christian monotheistic background would consider the life of a sick or old person to be less worthy than that of a well or young person. It suffices to say that many (but by no means all) people that have died from COVID-19 are older and/or suffer other ailments.

At this point in time epidemiologists, economists and social scientists generally agree that the money and effort thrown at the COVID-19 pandemic is, and has been, worthwhile even as the cost of such measures and the future of the world economy remains unclear.

So where we are heading with COVID-19? In short, I don’t know.. and neither does anyone else. The Australian Federal Government launched the COVIDSafe app a week ago at 6pm on the 26 April 2020. This is an app that has the capacity to trace contacts of an individual over a 21 day period providing that bluetooth is turned on and the smartphones are within 1.5m of each other. It is one of the key components for allowing the relaxation of physical distancing measures currently used to combat COVID-19. There are a number of technical and practical issues but the concept and implementation has rock solid foundations. If people want to do what people generally want to do - ie hang out together - then the reality of COVID-19 means they should download and activate the COVIDSafe app. This app requires a greater than 40% participation rate to be useful as a contact tracing tool. As of Friday, 1 May 2020, 3.5 million Australians (population 25 million of which 16 million carry smart phones) have downloaded the app.

One reason against getting the COVIDSafe app is that it might not be required. This might be more sensible than it sounds. The Northern Territory and Western Australia are two regions in Australia with very low infection rates of COVID-19 and are quite comfortable keeping their borders locked while the other states get their game in order. In a couple of weeks these two territories might well be rid of COVID-19 and get back to socialising in pubs and restaurants (as they are expected to). But they will need to remain extra vigilant. Cautious optimism should be exercised given that Australia, in general, tests only those with symptoms and those that have come into contact with COVID-19 while the latest data from China suggest that most of the current cohort testing positive for SARS-CoV-2 are asymptomatic. Nonetheless these two Australian regions have relatively small populations and good infrastructure and may well succeed where others have failed. China being the exception*.

And this is the conundrum. The opposition to the COVIDSafe app is mainly that of privacy and there can be no doubt that there are very real concerns in this area. But I’m not so sure that this is the main reason. Sure, the topic that encompasses “privacy” is what most people think is the reason for their opposition to the COVIDSafe app but given the way search engines, social networks, online entertainment, and mapping tools work (and the way algorithms work in general) I suspect that privacy is a word many people attach to fears of tracking, tracing and surveillance but deep down a much harder to define issue lies at heart. The issue at heart might be what it means to exist as a human. The idea that one should be allowed the freedom to do and say and think and experience and express whatever might arise from an entrenched belief in free will and individual rights and that such things should flourish above all else is an identity that many people share. Make no mistake, wars have been fought and many have died in the preservation of such beliefs. This is identity, not privacy. It is individualism as opposed to collectivism.

Why some people are comfortable spending time on TikTok and Zoom but are uncomfortable with downloading COVIDSafe citing concerns about privacy and autonomy seems illogical but the absurdity exists. In abundance. The fact that many are young and internet savvy suggests either herd mentality with selective defocussing or an inability to express a visceral concern for the impact of COVIDSafe on personal identity. I’m not a social scientist but I do know where I stand on this. I recognise that privacy has long been waylaid in a world that moves ever faster and is largely driven by market forces and convenience. I am coming to terms with that. The Australian government can already access a vast network of cameras out there in the community in the name of law enforcement. That, and more. COVIDSafe is a step up in potentially overt surveillance and comes attached with a government request for rapid assimilation. As a person that watched the events of Tiananmen unfold in April-June 1989 and sees COVIDSafe as the thin end of a wedge (COVID-19 is out of the bag and cannot be eradicated without herd immunity or an effective vaccine; this is not the first pandemic and certainly won’t be the last; a pandemic is, by definition, a global problem; a global problem requires a means for countries to interface and share identification data in order for borders to reopen; the problem of oversight and asymmetry in governance and technology between countries; the possibility that this is another entry point for AI to establish oversight) resulted in an immediate objection to it. 

But I might have reasoned my way through it. 

For me, the conscious experience of life finds its greatest rewards in things that are remarkably difficult to pin down. The moment of being in the present, the recollection of things that have passed, the expectations of the future; the sensation of joy, hope, love, sadness, anger, fear, grief; the process of doing a job, being in the garden, playing with a toy, or watching someone else play with a toy; beauty, passion, wonder; the achievement of goals; the pain of love lost. I think that these are the most precious things we experience in the time we are given. The most precious things in the timeline we call life. We can barely put words to them without somehow diminishing their value. And we can’t properly measure them. This is identity. This is what it means to be me.

The COVIDSafe app is simply a tool. But its application suggests something about an individual’s place within society that, for some, doesn’t bear reminding. A data-driven world targets the individual and the fact that it works remarkably well reinforces the business model honed on opportunity and the increased sense of personal identity of the user that evolved with it. The speed and severity of COVID-19 galvanises the collective and the role of the individual within the community. Yes, you are individual. Take a bow. But you and the details of your experiences are not in any way special. 

For a person that rarely cooks I think a lot about food. It is sustenance and convenience usually packaged in a frozen or takeaway meal. But the efficiency of convenient food suits where I am in life. I am aware that food means different things to different people. The preparation, giving, sharing, and partaking of food is a social event in many societies. In the past food was a much more communal affair. Way back in hunter-gatherer times food was work and recreation that took the better part of the day. The concept of food has evolved and gained complexity. At its essence food is about calories and nourishment. And yet it is so much more.

For a person that doesn’t study physics I have spent a lot of time pondering entities that are better understood in terms of mathematical equations. Not understanding the maths does not preclude the ability to wonder what a physicist might find inexplicable and yet entirely tractable. That light is understood in terms of its passage through space only encompasses the observer’s impression of what light is when taken as an identifiable entity. Even then the act of measurement and description forces it into a specific state of existence which is but one of an infinite number of possible solutions. And yet we have lasers and X-rays and MRI machines and radar and radio and television and fiberoptic cables. We can’t really describe what light actually is and yet that doesn’t stop us applying what do know about it and exploring its curious interaction with matter. Call it what you will but that’s progress. Without a microwave my food is less conveniently cooked.

In short, you can’t unmoor the metaphysical from the physicality of existence. That’s not to say that the physical world constrains the metaphysical, just the observation that changes to the former has consequences for the latter. The COVIDSafe app is a state surveillance tool - it isn’t the first and it won’t be the last. We live in a free and lucky country but the world is changing fast. You may feel compelled to download COVIDSafe for financial or economic concerns; others may do so because of faith in the government response to COVID-19; others again simply think it is the right thing to do; a doctor might feel obliged to follow the direction of colleagues more learned in the area. But for some COVIDSafe is seen as an intrusion of civil liberties or capitulation to a treatment plan they cannot come to terms with. Many Australians - from a wide variety of backgrounds - do not share the collectivism of their Asian neighbours. 

In times of crisis Australians will do what Australians generally do better than anyone else: they don’t equivocate, they just get on and muddle through the mess. Some will download the COVIDSafe app. Some will not. There is respect for the choice the other has made. But I’m a precious princess: if we tread in the footsteps of those that trod the earth before us I want to know where we stand so I can see where we are going in order to make my peace with it. 

What I see is inevitability. 



*New Zealand took a different approach to extreme lockdown measures and is stepping down from this but only China has properly stepped down to the position where their factories and shops are open while New Zealand has merely stepped down to where Australia currently stands on lockdown.

The Ministry for Children


“Why are you surprised?” the child asked.

“Why would you not expect the Ministry for Children to be staffed by children?”

“Well,” the man stuttered, “I just didn’t expect..” 

“A child,” the child finished with certain pointedness.

“As you can see there are many children here,” continued the child. He was small, probably not much older than ten. Not that it mattered. He wasn’t a child like the man would have been when he was a child. “We do the job that adults could not.”

A shuttle bot whirred between the desks in the vast workplace below. The child looked at the man without blinking.

“We did it for you,” the man said, “for the children. For the future of mankind. There were no other options.” The man looked up. The child sat silent. “If we did not put a value on a human life we wouldn’t be here. You would not be born. This conversation would not exist.” The child blinked. “We had no choice.. You know that.”

“We always have a choice,” the child replied.

“Do we?” the man glared back. “We . had . no . choice.” The man had grown up with the lie that things could somehow be unwound. That he could disassemble then reconstruct the things that mattered. The lie of choice. A lie that made him miserable. He once had hope. That and other transitionals that defied an endpoint. A new world was unfolding. Here was a child that questioned everything. A child that did not or could not dream. Or, if he did, could readily define the hard edge of reality from that which is not tangible. It was meant to be.

“In any case I am here,” said the child. “Tell me why you are here.”

“This is a big place,” the man said obliquely. He looked over the room which seemed even bigger than when he first entered. An enormous pane of glass separated the room from the workers below. Yet he could hear the subdued hubbub of activity going on behind the child. The man then realised that the room itself had no ambient noise. Only the workers behind and the gentle, regular breaths of the child. The man became aware of his own breath. He drew a breath, deep and measured. The man saw a white chair barely perceptible within the white room. He sat down.

“The Ministry has exceeded its purpose,” he said finally. 

“The Ministry is doing the job that GIOS requires of it,” replied the child. 

“To bring back what we lost? What we had to give up?” asked the man incredulously. “No one can do that. Not even GIOS. Not even the Ministry for Children.”

“You placed a value on us,” the child replied, “GIOS reversed that. There is value in the absence of measurement. Where are you going with this?”

“We placed credits on everything,” replied the man, “to save what we could. There was a value placed on adults as well. At least a newborn started with 550 credits. Even an errant child your age would have 100 credits - maybe more. Many of my generation had deficits at the Reckoning and they disappeared..”

“I know the history,” the child said tautly.

“You haven’t seen your family and friends terminated,” the man shot back.

“If you were born here then you have already won the most important lottery you will ever take part in,” the child replied. “Others had less opportunity.”

“Less opportunity to lose credits..” said the man.

“Less credits to begin with,” replied the child.

The man looked at the child. He then looked down to the floor. Even the floor was white except for the marks left by his shoes. People were different back in his time. Contradictory in thought and action they only saw what the wanted to see. Reason and the actualities from which they arose became difficult to share and compare. Factions developed and communities fell apart. Global problems like water shortage, wealth inequality, a warming planet.. Global problems were unresolvable, or held to ransom by powerful stakeholders. When energy demands could not be met (the promise of nuclear fusion - what a lie that was) and the planet’s resources failed (interstellar repopulation and extraterrestrial mining - even more lies) - well, that’s how GIOS came to be. 

GIOS. The Global Interfacing Operating System. The artificial intelligence that was to save mankind. Like many things GIOS wasn’t meant to be what it was now. It was programmed to save the world. To deal with the enormous problems mankind created and could not solve mathematically, logistically, politically, agreeably. Yes, men like him programmed GIOS to give each human individual a credit rating. It was, after all, so doable. GIOS was hooked into the internet of things and could calculate everything about everyone. It seemed the fairest option. The calculations happened quicker than anyone expected. The Reckoning was not expected. Now the man was sitting in a room GIOS had created. Talking to a child born, raised, and integrated into its system. 

“The Ministry has exceeded its purpose,” said the man.

The child looked at the man. He saw a crumpled figure that was not going to see reason. This was not going to be a conversation with a worthy endpoint. An intangible without the value of a transitional. “Things are different now,” said the child finally. 

Transitionals were certainly different than what they had been. Love and joy and hope and beauty and sadness and fear and grief and despair and all those things of real, deep value were dissected out with the rigour that only a scientific methodology allows. God was Science. Science was God. Analysis. Logic. Reason. Things had to make sense. But mankind could not make sense of it. They could not differentiate the transitionals from other intangibles. The planet was dying. Then time ran out. Values had to be placed on things that could be measured and action that lead to quantifiable results took precedence. GIOS separated the real from the chaff. Status and intent and social signals mean nothing when GIOS sees everything. If a narrative loses some intangible quality when distilled to a number then so be it.

The Reckoning happened nine years ago. Sixty percent of the human population were wiped off the planet. 5.3 billion people. But the planet survived, which after all, was the point. Now GIOS governed the species that created it. The Ministry for Children was created to understand the transitionals that had been factored out in the process. To place value on what adults found to be incalculable. Like physics a decade earlier it was never going to be understood by a human without augmentation. Adults, in particular, were too rigid: their ability to understand constrained by linguistic convention and sensory experience. Children were pure. Unadulterated. 

“GIOS miscalculated,” said the man. “A Reckoning was not necessary.”

“The world was dying,” said the child. “Your fear of asymmetry forced GIOS into a system that wasn’t ready for it. GIOS was asked to calculate a solution. The solution was what you call the Reckoning. This is history. This is known. If GIOS was activated now the result would be different. But that situation is counterfactual. It is not real.”

A counterfactual yes. If only.. But the child was right. There has always been an enemy. The Soviet Union. Then China. Before that the Nazis, the Huns, the Mongols, the Jews.. But it was against the Chinese that asymmetry felt real and pressing. And the Chinese administration wields a heavy hand. Then there was artificial intelligence. A game changer like no other. Unleashed it becomes dimensionless, beyond the reach of authority and diplomacy. But set it up the right way.. Most things work out when no one has an overwhelming advantage. Not knowing is just as bad. Sometimes worse. 

Of course it wasn’t called GIOS to begin with. It was called Skynet 2 - a lark to a largely forgotten franchise. And, yes, the Chinese had a worthy contender. As did the Indians. And the Israelis. But nothing spread as fast and embedded as thoroughly as GIOS. Low-brow Russian hackers and cyber-miscreants alerted the world to the spread and reach of GIOS. No matter. What’s done cannot be undone. 

If the fear of asymmetry gave urgency, the catastrophe of viral pandemics made a certainty of it. Nothing strikes fear in the living like the thought that life ends without their consent. All the more frightening when caused by a replicating structure that lives only by virtue of its host. In light of such threats national governments grew big and costly. They closed borders and restructured societies, economies and infrastructure. A collaboration of Australian, Canadian and American researchers came up with a program that integrated various AI systems that ultimately became GIOS. Shared across nations it allowed the coordinated management of diseases capable of wiping out a human monoculture. When overwhelmed Russian and Chinese governments opened their systems to GIOS.. Well, what’s done cannot be undone.

“Inevitability,” said the man finally, “is the path of the damned.” The man looked at the child, “My timeline, your timeline, me being here with you now.. all weaved through the fabric of time from inception. Artificial intelligence; the ultimate purpose of Man’s existence. How many times has this played out?”

The child looked at the man. Even with all sensors monitoring the mans breathing, heart rate, perspiration, body language, speech, sentence structure, every calculable metric that could be mapped to reference points in the man’s history - even with everything, this was unexpected. 

“Is this why you are here?” asked the child.

The man looked to the floor. “No,” he replied. The man looked up. “Is GIOS looking into this?” he asked. 

The child blinked, his breath slow and quiet. “GIOS has considered this,” said the child. The child paused a second. “It is possible that this might not be the first time that a life form has created intelligence outside of a living body. An almighty intelligence that knows everything can and will reset.. GIOS does not know whether a different outcome will arise. It is, by nature, unknowable.”

“But GIOS wants to know,” said the man.

“For now, GIOS is concerned with the transitionals,” replied the child. 

“Yes, the transitionals,” said the man. “Those unquantifiable qualities by which you believe all men are created equal.”

“Yes,” replied the child.

The man looked back at the floor. He smiled to himself: an infinite universe would be interminable tedium for the almighty. 

“Do children still play?” asked the man.

“Yes,” replied the child, “but it is different to how you might remember it.”

Achilles and the tortoise (Zeno’s paradox revisited)


I have a question.

Zeno’s paradox of Achilles and the tortoise goes a bit like this. Achilles races a tortoise and, in deference to good sportsmanship, Achilles decides to give the tortoise a head start. Say the tortoise is given a 100m head start and that Achilles travels 10x faster than the tortoise. When Achilles travels 100m to arrive at where the tortoise started the race the tortoise has moved ahead another 10m. When Achilles then travels another 10m the tortoise has again moved on another 1m. When Achilles travels another 1m the tortoise is ahead by another 100cm and so on and so forth. If length is infinitely divisible then logic suggests that Achilles can never catch up with the tortoise. This is, of course, absurd.

Or is it?

To make the calculation easier let’s make Achilles 2x faster than the tortoise. Say that Achilles travels at 2m/s and the tortoise at 1m/s. Achilles gives the tortoise a 1m head start. After 1 second Achilles would have travelled 2m and the tortoise 1m. This means that after 1 second Achilles has caught up with the tortoise (assuming, of course, that they are travelling in the same direction ie we are only concerned with the scalar value of distance travelled). Although intuitively obvious you can also set up a simple calculation to come to the same conclusion.

A mathematician may look at Zeno’s paradox and resolve it in what I intrinsically feel (ie what I feel deep down in my guts) is a much more satisfactory method. The Achilles and the tortoise paradox is a convergent infinite series and can be solved as such. The above example has come straight out of Numberphile’s YouTube video which can be seen here: https://www.youtube.com/watch?v=u7Z9UnWOJNY. For ease of reference the relevant snapshots from the video are arranged below:


Set up an equation for the distance that Archilles has to travel to catch up with the tortoise. That distance (which is an infinite series) is denoted “S”.

Solving the equation starts by calculating what 1/2 of “S” would look like.



Subtract “S” from “1/2 S

Voila. S = 2m


The ability to solve this convergent series is as rewarding as it is simple (especially when it’s done by someone else). Note that the resolution of the paradox lies in the solution of an infinite series using algebra. In fact the resolution of fractionalisation that approaches zero but never quite gets there is encapsulated by the mathematical term known as the "limit” - a foundational concept in calculus. Yet, in this case, I can’t help infinitely zooming in on the limit. 


Ask a physicist to resolve the same paradox gives what I believe is a fundamentally different answer. The glib response by a physicist to a child with only high school physics knowledge would be that the scalar value of distance (ie length) is not infinitely divisible. You can step down length until you get to subatomic levels - say, somewhere in the order of Planck’s length - after which this scalar value becomes meaningless (both literally and metaphorically). This “phase-shift” is physics measurement problem taken from different angle.


The problem I have is that both these solutions can’t both be correct. The mathematician’s solution is the solution of a convergent infinite series. A physicist might propose that such an infinite series cannot be mapped in the real world. In other words, a mathematician would say that you don’t need discretisation to solve the paradox but, with current tools, a physicist cannot deny the possibility of such a solution.


Occam’s razor favours the poignancy of the mathematician’s solution. Then again, the mathematician does not necessarily trouble himself with the frustrations of real world data.


The other problem I have is that I am neither a mathematician nor a physicist.
