Yes, what “AGI” refers to on LW is typically something far more powerful than what you describe. And yes, this causes a lot of confusion from time to time, when people confuse it with artificial intelligence in general (I’ve made this error more than once), which is one reason I often try to talk about “superhuman optimizers” rather than “AIs” in the LW context. (I often fail.)
