I think this is right, but it can be stated more simply as companies hire to invest in growth, and they conduct layoffs when growth slows (not because of AI or "improved productivity"). Everything else is storytelling and emergent phenomena.

Incentives in companies are such that there is never a shortage of people pitching projects that require more headcount. Growth justifies the decision to hire more headcount, but the connection from increased headcount to growth is tenuous and usually difficult to impossible to demonstrate with any real confidence. It wasn't so difficult pre-industrialization, but mechanization, automation, computerization and now AI have progressively made it harder and harder to really understand the economics of labor. You do need to hire people to pursue new areas, but also every incremental person adds to communication overhead. The effects of this depend on the org structure and the operating environment over time, so what may have been a good idea at the time can flip to net negative due to outside forces beyond the control or foresight of any decision maker. This explains why companies do layoffs while still hiring at the same time.
