Because companies have been talking up how their adoption of AI is going to make them faster and more able to capitalise on opportunities in order to prop up their valuations for a while now and it seems to work as far as share price goes.

Being able back up this talk with metrics showing that their employees are all in on AI reinforces this, since the share price is the metric the business optimises for over product development employee reviews will index on this over cost effectiveness, and at most big tech companies engineers are very much making every decision with an eye to performance review optimisation (i.e. how it will affect their next review rather than the product they are building)

There is also some lesser incentives in that meta employees care directly about the meta share price since a lot of their compensation is in the form of RSUs.

I’m not condonig this as a desirable state of affairs, just explaining the incentive curve that the actors are following.
