Agree. I am not an expert on AGI, but I suspect this route is a dead end because I believe true AGI requires interaction with an external environment to learn eg there needs to be a feedback loop to external things that it can interact with and learn from.
“You learn best from your mistakes” comes to mind here.
And not just shallow feedback loops but bigger, more profound ones eg “I didn’t go to work for a month and so I was fired and and now I have no money and it will now be hard to be hired again”.
