My question is inspired by an Internet poll[1]. When it appeared on HN two years ago[2], 45% voted that, yes, we are living in a simulation (of 14,463 votes at the time). When I checked back just now, about half (51%) still voted yes, but now at 4,111,498 votes.

Whether we are living in a computer simulation is indeed a fascinating question, and I’m not dismissing it, but there’s no proof or experimental evidence for it as far as I know.

I know about the simulation argument[3], but that’s not a mathematical/physical proof or an experimental result. Lots of brainteasers and paradoxes have arguments structured like the simulation argument; one example is Olbers’ paradox: Why is the night sky dark if there is an infinity of stars, covering every part of the celestial sphere? The argument about the stars seems to make sense but it doesn’t count as proof or experimental result, and we know it’s not true.

So I’m wondering how and why so many people are now convinced that we are living in a simulation?
