If you have 10PMs and 90 devs today, and go to 8 "hybrid" PMs + 2 specialized PMs, you're probably still creating backlog items faster than that team can close them.

So you end up with some choices:

* do you move at the same speed, with fewer people?

* do you try to move faster, with less of a reduction in people? this could be trickier than it sounds because if the frequency of changes increases the frequency of unintended consequences likely does too, so your team will have to spend time reacting to that

I think the companies that win will be the second batch. It's what happens today, basically, but today you have to convince VCs or the public market to give you a bunch of more money to hire to 10x the team size. Getting a (one-off?) chance to do that through tooling improvements is a big gift, wasting it on reducing costs instead of increasing growth could be risky.

A 70% reduction in the labor force of product and engineering has a lot of consequences.
