Why are you on a thread about AGI then? No one has built it so it's automatically what you don't want.

I don't want anyone talking about the dangers of nuclear war unless they built a nuclear weapon before

In that case, if anyone does ever figure out some safety reason for why AGI shouldn't be built, I guess you won't be hearing from them.

Look up who the author is. He helped coin and popularize the very term AGI, ran the AGI conference series for years, and his entire professional career is working this problem.
