AI, when it was originally coined, was equivalent to what is meant by AGI now. Through enough hype and misapplication of the term to any new algorithm, AI eventually acquired in practice the meaning "any new nontrivial algorithm that does things that humans can perform" (until the shine wears off, in which case it's no longer AI - even A star was originally considered AI). Looks like AGI is going to go down the same path. I wonder what the replacement term for AGI will be.
