Additionally, there's a limit to how much "productivity gains" on the tech side can cause actual positive business results. Going from an ugly, slow website to a fresh one will only increase revenue a small percentage, same with building a better shopping cart, fixing some obscure errors, etc. The majority of the web already works pretty well, there is no flood of new revenue coming in as a result of the majority of tech innovation.

Which means that after a brief honeymoon period, the effect of AI will be to heavily reduce labor costs, rather than push for turbocharged "productivity" with greatly diminishing returns.
