They lay people off and look good in front of investors. Then they hire people, talk about "growth", and once again look good in front of investors.
This would never fly if stock market was rational. But it never is.
And if/when companies need to scale back their ai investments they can spin it too and the stock market will eat it up.
They are just being AI efficient, and doing more while spending less on it :)
I wonder if this will happen before they have some obligatory debloating of the investors exposition to the company.
