This seems crazy to me. I am a PM and I am busier than ever. People are waking up to the idea that code is cheap and things can change faster now, so deciding _what_ to make and prioritise in the deluge of ideas coming to prod is becoming completely essential.

They don't seem to have taste when it comes to engineering either, but tbh 'taste' is a computable function, and will eventually be learned.
