Depends on your product strategy. If you only care about how your model will be used in the context of a harness (perhaps, specifically the harness that you designed), then the incentive is plainly there to optimize the weights within the context of the harness.

So you believe LLMs (despite their inherent deficiencies vs EBMs [0], etc.) can lead to what you'd consider AGI, but you also admit that there is no agreement what AGI actually would be and you further don't provide your own definition? But you are surprised that some (like e.g. Yann LeCun (I am very convinced by his published works beyond his authority in the field, but am willing to admit his could be seen as a biased position)) are skeptical?

If you provide what you'd consider AGI, we may not agree on that definition, but I and other skeptics could at least discuss with you whether A.) that seems reasonably achievable given LLMs inherent limitations and B.) whether any of what you'd listed is actually likely to get us there.

As it stands, neither is possible without knowing what you believe AGI to be, but for what it's worth, coming from someone who both does see LLMs as valuable tools but whose definition for AGI also contains, among other things, reliable self-assessment of factual uncertainty [1] and basic counting and grade school maths [0][2] without tools or eternally scaling training data, I have yet to read any evidence that LLMs can achieve my, rather strict, metric for AGI.

These models are amazing tools, their ability to leverage massive amounts of high quality training data to further sciences truly awe inspiring, but that does not mean intelligence, at least in my definition that requires some internals these models have never been proven to possess. It's nuts that solving Erdos problems can be done by a model which struggles to count or solve a sudoku without external tools, but that's where the technology has been for years now and no paper I have read has shown that LLMs can overcome that to any scalable degree. You can push further with training data, but the limitations remain, albeit less noticeable. Any externalities, be it tools (self-scripted or called by the model), external memory solutions of all shapes and sizes, etc. I personally also feel cannot be required for or lead towards AGI as intelligence may be better leveraged by such externalities, but should never require them, so much of your suggestion I feel shouldn't be considered even if one believes LLMs can yield intelligence. I will admit that I am very extreme here though, this is not a position held by everyone for good reason. At the end I will always point towards the "extraordinary claims require extraordinary proof" of it all and that LLMs, in the face of any doubt, should be viewed akin to how Stockfish can play better than any grandmaster, but that does not mean intelligence, at least in my world.

If your definition for intelligence does not require basic arithmetics or an understanding of ones own knowledge gaps, then maybe LLMs can achieve that, but I'd push back on that truly rising to the AGI moniker. Maybe a more comprehensive or even my definition of AGI is possible whilst keeping the autoregressive nature after all, but there is no evidence supporting that by itself and quite a few things that haven't even begun to be overcome before something of that magnitude could be honestly considered.

It's akin to "let's colonise Mars by 2020 or 2030 or 2040 for sure, then terraform it" proposals. If that were possible, wouldn't we see a lot of these methods applied on earth and in a moon base long before (as in, we'd have had a permanent moon base in the early 2000s)? Same with LLMs, if they can truly yield AGI, we'd see some of the major deficiencies dealt with long before. The fact that we neither are terraforming earth, nor have any permanent off world colonies, nor have solved some of the listed, inherent limitations with LLMs by their design, that's what informs my skepticism that both are reasonably achievable in the timelines some industry "experts" (read hype merchants) propose on the regular. You tend to see some progress, a path toward solving actionable problems long before full implementation, at least in the real world...

I’m afraid it’s a terrible metaphor, starting with the fact that LLMs are nothing like electricity, and the relation of harnesses to them is nothing like that of electronics to electricity, save perhaps one is a prerequisite of the other.

Harnesses (and the concept of agents before them) presuppose competence in LLMs which simply doesn’t exist.
