I'm a full stack developer. I thought I was going to agree with the article, at least for some parts, but I actually disagree completely. What the article says is true, but you could replace fullstack with any other role, name the article "You'll never be the best" and the article would still be true. Even if you specialise in something, there will still be others that are better (and if they ridicule you, they are just assholes) and more things to learn anyway. The author is mentioning a lot of specific technologies (react, databases, python) that, even as a pure "backend engineer" or even a "database specialist" would still face the issues mentioned in the article. Specialising and going deep is great, as staying broad and doing more stuff. You just need to understand where you stand and what your strengths and weaknesses are. You can always specialise more, and more, and more. Specialise in backend, or actually .NET development, or actually databases, no I mean SQL, actually I mean scaling SQL databases, etc.
