It's time to rethink the term full stack.
I say this with some ambivalence because I helped to popularize the concept. The website full-stack.com was my take on the state of the art in 2009. But sadly in 2019 it's a relic suitable for the Computer History Museum.
One of the great things about the 2020 Stack is that it's not one size fits all. Mix and match is the game. As your project grows your 2020 Stack grows with it. I've got my perfect stack, and you've got yours.
I'm curious to see what your perfect 2020 Stack looks like.
