I’m pretty the curvature of the universe has actually been measured to be very close to 0, within margin of error, which would suggest an infinite universe. (It doesn’t prove it by any means, though. The curvature could just too small to measure.)
However, the observable universe is indeed finite, due to the speed of light being finite.
I am one of those people who’s pretty concerned about AI, but not cause of the singularity thing. (the singularity hypothesis seems kinda silly to me)
I’m mostly concerned about the stuff that billionaires are gonna do with AI to screw us over, and the ways that it’ll be used as a political tool, like to spread misinformation and such.
