This is the "build it, they will come" argument. It doesn't work.

The idea is that if you put a bunch of great engineers in a room they'll make a brilliant product. Except they never do. They make something very clever, that does something brilliantly, but it's almost always the wrong thing. Engineers don't like talki g to customers, or discovering requirements, or running user focus groups. They want to build what they believe people need, which is very often not what people actually need. And they take far too long to do it because they're focused on perfecting the tech things instead of shipping.

Engineering teams need product managers, a QA team, technical writers, customer success people etc. Some engineering teams also need project managers too if they're no good at self-organising.
