That's a very based take!
The whole idea of a PM boils down to address a less qualified non technical middle man to make all the important decisions, while also pigeon hole your communications with the rest of the stakeholders.
Why does this role even exist is beyond me.
It's like we can't trust the engineers with any important decisions, so we need some business guy who took a two week course and now is suddenly qualified to be calling all the shots.
Dev + Business = speed and customer centric
Dev + PM + Business = one more layer, i.e. slow, i.e. some loss of customer voice
I worked at Amazon as dev for 10 yrs. In early days 2001+. Amazon did not hire PMs then. Best of Amazon exp came out in that period. I was part of that myself. Pm is needed for things like building amazon prime. If at all.
