I actually really disagree. I think that's a VERY plausible way for a true AGI to come about. In fact, prior to LLM's I used to think that was the ONLY way we were going to get an AGI.
We know humans are AGI's. If it were possible to upload your brain to a computer, and then make modifications to enhance your speed of thought and intelligence, of course you would do that. It actually makes a LOT of sense if you'll admit the technology necessary to do that.
In fact... uploading your brain to a computer is probably the most natural progression of intelligent life I can think of. It solves SO many problems. Biology is fragile. Brains cannot be replicated. But data can. A probe can travel the galaxy. It's not limited by biological lifespans and life support.
