And the worst case downward spiral will involve not only a surge in supply but a drastic drop in demand to go along with it.
All of those previous "knowledge workers" scurrying for the trades not only become more labor supply, but without their cushy jobs they will no longer be able to afford to hire trades people to prop up the demand side.
Double whammy.
Citation needed. Again, I wanna emphasize that I'm not saying it won't happen. I'm just saying that it's not a given that it will.
There is very little sign that current models can do anything but (at best!) augment most knowledge workers (with some exceptions). And there are very reasonable open questions about whether it's economically, and ecologically, sustainable to continue development at anything near the current pace. There is, in fact, plenty of indicators that even the current SoTA is the result of a financial overexertion.
