"Now let it work. Mischief, thou art afoot, take thou what course thou wilt!"
But seriously, it isn't on me to justify my skepticism of the extreme claim, "We are in a race to build machine super-intelligence" because that skepticism is the rational default. Instead it's the burden of people who claim that we are in fact in that race, just like "self driving next year" was a claim for others to prove, just like "Crypto is the future of money" is a statement requiring a high degree of support.
We've seen this all before, and in the end the argument in favor seems to boil down to, "Look at how much money we're moving around with this hype" and "Trust us, the best is yet to come."
Maybe this time it will.
