I just disagree that we have to intentionally create them -- I think there are a lot of places we can experimentally bruteforce the implementation instead of having a solid theoretical understanding if our only goal is creating an AGI.
I don't think we need any theoretical breakthroughs, per se, but rather, a lot of computing power and time. No one seems willing to take a million nodes and run them for a decade to brute force some of the mechanisms -- everyone wants results on the short timelines that grants or Wall St operate on. I get why, but that bias towards quantifiable short-term gains fundamentally limits the search algorithms we're implementing in our quest for AI, and likely means that we won't get there in a meaningful way, because intentionally implementing the necessary requirements is a fool's errand of complexity.
In short: we're not smart enough to do the simple, but slow thing, so we're trying the highly complex one with demonstrable incremental results. I expect this approach to continuously fail to develop AGI even while it demonstrates results on discrete problems.
