Why I'm still bearish on LLMs after Navier-Stokes

    The premise in the very first point seems off:

    > the frontier labs are priced according to the narrative that they have produced or will in the very near future produce a fully automated drop-in replacement for most knowledge workers...

    Even assuming this is how the AI companies are being valued (they're not), the numbers are off.

    The "value" of most knowledge workers -- based on what enterprises currently pay for them -- is $50 - 70 trillion annually. It's reasonable to assume that if AI drop-in-replaced all those knowledge workers, AI companies could credibly charge somewhere in that order of magnitude, because that's what the market is already bearing.

    So if their hypothetical revenues are double-digit trillions and valuations are some multiple of that, the entire AI industry would be valued at double-digit trillions at the least.

    Yet cumulatively the industry (the frontier labs + the SWAG estimate of the AI parts of all the other players) are valued at, say, ~6 - 7 trillion? Which seems like a fair approximation of how much knowledge work they can currently automate.

      This assumes you don't change the market, but at the scale of (checks notes...) "all knowledge work", that just doesn't hold.

      For example if you put 1bn people out of work, you now need some sort of safety net to bail out much of that workforce, a truly unprecedented change. You also lose tens of trillions of dollars of tax revenue.

      One solution might be to recoup that cost and lost tax revenue from businesses by raising corporation tax. If corporation tax went from low tens of percent to high tens of percent, would those businesses be able to afford all that AI? No. Same order of magnitude? I doubt it.

      There are many possible futures there, but the simplification made in the parent comment is completely unrealistic. The article is right in calling out the valuations as crazy.

        Yes, posted it elsewhere: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=49722616">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=49722616 -- this is necessarily a simplistic analysis to address a simplistic point in TFA, but it still kinda-sorta works assuming AI only augments workers and does not replace them wholesale.

        However, I fear reality will be much hairier.
