The economy has taught us that when there is an excess of worker productivity, it leads to layoffs. It certainly does not lead to raises.
If AI coding improves productivity, it might move us closer to having 2X as much work as we can possibly do instead of 3X.
Nowadays we already have bullshit jobs that keep academics employed. Retraining takes several years.
With "AI" the danger is theoretically limited because it creates more bureaucracy and reduces productivity. The problem is that it is used as an excuse for layoffs.
The normal conversation is that productivity growth has slowed and the divide has increased, not that more productivity creates lower outcomes in real terms.
