Amazon still has pockets of very deep expertise with highly technical leaders that make for very productive and profitable teams. I've personally worked with some OR and Economics teams that consistently deliver exceptional results for the bottom line. And I know that many of Amazon's best businesses have come (originally) from organizations like these: AWS, Kindle, Echo, etc. But it very quickly is moving away from that idea and toward a world in which MBAs with half baked ideas that don't pass basic sanity checks are allowed to commit to impossible (P=NP!) ideas on behalf of their teams. And it destroys morale: nobody wants to work on a project that is known from the start to be impossible to deliver as specced. So they churn out. And when you talk to the goon that is in charge of it all, the problem always magically seems to be that they can't hire fast enough.
