I've seen this enough to know where it goes - companies will move mid level jobs offshore, then relocate their "HQ" from a cheap midwestern city to an expensive one, NYC, Austin, LA, etc. Basically, the executives want to live somewhere expensive and cosmopolitan but they don't want to pay normal workers enough to live in those locations.
I think what you're seeing is change for the sake of change. You're friends will probably find jobs as "AI Engineers" at another company who just did a massive round of layoffs.
