There are valuable uses of learning models, but I'd say they all have the following constraints:
We're not currently on a trajectory toward automata like that, at least not with the kind of AI that's currently heavily being invested in, but even if we were, it would not lead to a positive outcome with the way society is set up right now. The problem is that someone would own the automata and therefore be in complete control over in whose benefit the automata would work. Unless the automata are easy to make (and the patents easily bypassed), making it difficult for someone to monopolise them, it would take a fundamental change to the way the economy works for this to benefit everyone, and that's not an inevitability.
But this video isn't really about that, it's about the much more likely scenario that AI does not end up living up to its promises and the money eventually running out, and what the economic fallout of that will be.
The biggest issue with the three-pedalled bicycle is that humans have, at most, two legs.
I would argue that's actually the last situation you'd want to use an LLM. With numbers like that, nobody's going to review each and every letter with the attention things generated by an untrustworthy agent ought to get. This sounds to me like it calls for a template. Actually, it would be pretty disturbing to hear that letters like that aren't being generated using a template and based on changes in the system.
Seems to me that the "market performance ratio" should weigh a lot heavier. The whole thing that makes something a bubble is that a lot of money is being put into it while very little is coming is coming out and there being very few prospects of that changing in the near enough future outside of religious conviction, yet this metric is the only one suggesting that investments creating real value should matter and it only accounts for 7.5% of the whole score. Then again, the site doesn't actually properly define what "market performance ratio" means and doesn't state its sources beyond a vague description.
Also, the person who made this, Mert Demirdelen, is "head of growth and product" at Mobiversite, an AI app maker. His skills listed on LinkedIn include "AI" and "Blockchain". So maybe not someone who is completely devoid of the desire to invoke a particular impression of the state of the AI economy.
