The takeaway is: If you are to judge LaTeX, judge its whole ecosystem.

Otherwise, this is like saying Python is not suitable as HTTP client because "urllib" has too many quirk - ignoring the fact everyone else uses the excellent "requests" libraray.

Although there are interesting developments at its code (XeLaTex, LuaTex), it is the packages which are ever evolving at a rapid pace. Have trouble with the "graphics" package? Use "graphicx" instead. Don't like the old "letter" class? Use "scrlttr2". And of course, use TikZ, it is one of the most well-designed, best-documented and comprehensive packages out there.

Compared to most programming languages, what I really like about LaTeX is their almost almost merciless take on backwards compatibility. This means that your old "article" document almost certainly works with later LaTeX versions. There will never be a breaking new version of "article" that forces you to adapt your LaTeX code, like we see with so many libraries in other languages. But this also means that you are stuck in your "old world" if you don't keep your eye open for new packages, and are willing to learn them. There are quite a lot of StackExchange questions that are essentially like this:

"Q: How do I fix my issue with package X? A: Use the newer package Y instead (or in addition)."
