I'm sorry, imo those are two contradicting sentences.

But it might be related to a personal pet peeve of "full stack" developers claiming to be expert in most moving parts of the stack.

Only to post on medium this amazing db hack they found, to be called out in hn comments for not reading the basic docs of one of the core items in their stack.

I always look at Doctors for a bad analogy; why full stack developer is a bad idea. Sure the heart surgeon will be able to diagnose your broken leg. Might even be able to assist you with a cast. But trust him to operate? There a specialist for that!

Is this not the same for dev work? Designer, Developer split into 4 fields(desktop, mobile, frontend, backend), database admin, sys admin. All possible to be done by a "full stack" developer.

But I don't see you become a specialist or expert in any of the fields of your stack, if you don't dedicate to a few.

Well, there is a reason why in some countries access to specialists is forbidden unless you are checked by a general physician first, the one responsible for being your official doctor throughout your entire life.

He knows best than having people searching for specialist by themselves.

As for myself, if you prefer a more descriptive example, I specialize in everything related to Java, .NET and Web (VanilaJS) stacks.

As a citizen of one of those countries, this fails spectacularly when your family doctor does -not- know best or just doesn’t care about his job, yet due to the huge scarcity of family doctors, will never lose any of his clientele.
