The dangerous window may not be an evil superintelligence, but the gap between AGI that can automate jobs and superintelligence that can deliver abundance.
What worries me is the period after you have the first human-level AGI but before you have a superintelligence that can bring massive abundance. You’ve got an AGI that can in principle automate almost any job and is crunching through one industry after another, but you don’t yet have the superintelligence that can airdrop a molecular nano-assembler in everyone’s backyard. What happens to the world economy in that interval? Who gives universal basic income in the Central African Republic?
