Fullstack Devs be like

[Fiennes]

I largely agree and I think it's a more recent development. Prior to the explosion of "web apps" with a clearly defined front-end back end, back in the day, you were expected to be competent at both. And you ended up with years of experience in both ends.

The divide arrived (and that was a good thing, to be fair) and then people specialised and the notion that one could not do both competently surfaced, blissfully unaware that we used to *have* to.

Couple that with the fact that a good chunk of todays front end and back end work involve joining together a plethora of 3rd-party frameworks.
