Essay by Phil Torres: “The point is that longtermism might be one of the most influential ideologies that few people outside of elite universities and Silicon Valley have ever heard about. I believe this needs to change because, as a former longtermist who published an entire book four years ago in defence of the general idea, I have come to see this worldview as quite possibly the most dangerous secular belief system in the world today. But to understand the nature of the beast, we need to first dissect it, examining its anatomical features and physiological functions….
Why do I think this ideology is so dangerous? The short answer is that elevating the fulfilment of humanity’s supposed potential above all else could nontrivially increase the probability that actual people – those alive today and in the near future – suffer extreme harms, even death. Consider that, as I noted elsewhere, the longtermist ideology inclines its adherents to take an insouciant attitude towards climate change. Why? Because even if climate change causes island nations to disappear, triggers mass migrations and kills millions of people, it probably isn’t going to compromise our longterm potential over the coming trillions of years. If one takes a cosmic view of the situation, even a climate catastrophe that cuts the human population by 75 per cent for the next two millennia will, in the grand scheme of things, be nothing more than a small blip – the equivalent of a 90-year-old man having stubbed his toe when he was two.
Bostrom’s argument is that ‘a non-existential disaster causing the breakdown of global civilisation is, from the perspective of humanity as a whole, a potentially recoverable setback.’ It might be ‘a giant massacre for man’, he adds, but so long as humanity bounces back to fulfil its potential, it will ultimately register as little more than ‘a small misstep for mankind’. Elsewhere, he writes that the worst natural disasters and devastating atrocities in history become almost imperceptible trivialities when seen from this grand perspective. Referring to the two world wars, AIDS and the Chernobyl nuclear accident, he declares that ‘tragic as such events are to the people immediately affected, in the big picture of things … even the worst of these catastrophes are mere ripples on the surface of the great sea of life.’
This way of seeing the world, of assessing the badness of AIDS and the Holocaust, implies that future disasters of the same (non-existential) scope and intensity should also be categorised as ‘mere ripples’. If they don’t pose a direct existential risk, then we ought not to worry much about them, however tragic they might be to individuals. As Bostrom wrote in 2003, ‘priority number one, two, three and four should … be to reduce existential risk.’ He reiterated this several years later in arguing that we mustn’t ‘fritter … away’ our finite resources on ‘feel-good projects of suboptimal efficacy’ such as alleviating global poverty and reducing animal suffering, since neither threatens our longterm potential, and our longterm potential is what really matters…(More)”.
