As someone who jumped on the C++ train with C++98 and did my best to keep up since then, at some point around C++17 I gave up out of the sheer headache of having to reread entire manuals about how to avoid pitfalls any time I have to do more C++. None of the other languages I use exact such a heavy toll when you're rusty and need to reacquaint yourself.

I've written more C++ since C++17 because that in those cases it was the best tool for the job, but, man, every time I do it I feel a strong urge to just burn it all down.
