That's never quite how it happens, they can't let go. You can see it in the "Office of the CTO" thing. I've seen that one many times before: when confronted with the endless complexity and depth of building a real global product, they recoil. Everything takes too long, is too uninteresting. They instead build up this parallel engineering organization that is showered with money, headcount and C-level attention to build the new moonshots, with the subtext that whenever it's "ready", it will be thrown over the wall to the actual engineering org. It's a speedrun to make your engineering talent leave.
