Just a quick note to say that I think planning on a pivotal act is risky and dangerous, and we just don't yet know how feasible or infeasible "some healthy and competent worldwide collaboration steering the transition" is - more research is needed.
As I say in The Rival AI Deployment Problem: a Pre-deployment Agreement as the least-bad response,
"while it may seem unlikely at this stage, a predeployment agreement might be the least-bad option – and at least worthy of more study and reflection. In particular, more research should be done into possible clauses in a pre-deployment agreement, and into possibilities for AI development monitoring and verification."
Strong endorse. I have, on the occasion of two lightning talks (Bahamas and EAGxSingapore) and a shortform post, claimed that lock-in risk obliges us to reject positive longtermism (fighting-for) and constrict ourselves to negative longtermism (fighting-against). However, I point out near the end of each lightning talk that suffering-focused views present me with an extremely difficult challenge: that preserving the future's freedom preserves the possibility of torture, that suffering abolition is a form of positive longtermism. I really struggle with the tradeoff between libertarianism/cosmopolitanism (or any other framework behind emphasizing lock-in risk) and suffering-focused views; by far, the button-offering demon that presents me with the most dread is the one offering a button that would end suffering but lock in my particular opinions and aesthetics about what flourishing is.
No top-level post about positive and negative longtermism yet, though.
