Given that someone has to operate this REPL and compiler, the I is that someone. A system that can do that without an operator would be a decent step forwards.
Like, the task I sketched out is the bare basic sketch of what you can ask a new grad/hire to do. Which ends up being ~80% of their job anyways. I really don't think the average person could do that task (unfortunately).
If the new Claude code stuff honestly can do this, then, like I said, that's a close enough definition of AGI for me.
"It's life jim, but not as we know it" -Bones, probably.
I've seen some hokey definitions, but a 3 expression inductance clause is pretty low bar. On that score, your REPL and my compiler are AGI.
