No, people in power — the CEOs of those companies — did notice. It is a feature, not a bug, from their perspective. It makes the employees cheaper since they don't need to be provided benefits.

I don't see how an automated implementation of the same feature/bug is an improvement over the manual implementation. Either way, it's a deliberate choice that minimizes the value provided to one set of people (low-level employees) and maximizes the value to others (shareholders and executives).

I don't see how using automation and AI to increase the efficiency of transferring money from the poor to the rich is an improvement.

It's perhaps instructive when people think "people" works as an abbreviation for "people in power".
