From McCarthy's reply:
My current answer to the question of when machines will reach human-level intelligence is that a precise calculation shows that we are between 1.7 and 3.1 Einsteins and .3 Manhattan Projects away from the goal.
omg this statement sounds 100% like something that could be posted today by Sam Altman on X. It's hititing exactly the sweet spot between appearing precise but also super vague, like Altman's "a few thousand days".
