Does the source matter?
AI is a simulation of intelligence. It’s right there in the name: artificial — not real — intelligence.
AGI, or Artificial General Intelligence is “a type of highly autonomous artificial intelligence (AI) intended to match or surpass human capabilities across most or all economically valuable cognitive work.”
A good way to think of it is that AI tends to be single task or limited in task focus, whereas AGI is, again by its very name, general purpose, where “general purpose” translates to “anything humans could choose to do”. I’m not sure I concur with Wikipedia’s inclusion of “economically valuable”, though.
But when questioning whether it’s actually intelligent, that pesky “A” is still there.
The real question should be: does it matter?
