That is code for "it is evolving and I cannot be bothered to keep up".
All languages that are actually useful evolve. They get features that other people need, and you don't, just yet. Some of those features do turn out not to be perfect, because they are made by humans.
Comparing an old language to a new language, the new language will have many fewer of those both because it leaves many old things behind, and because it gets benefit of hindsight for the rest. Give it time, and it will accumulate "incoherence" of its own; the faster it evolves, the faster that happens.
The alternative is for a language not to be used. Then, it can stay pristine and "coherent", and not useful.

No, I actually teach C++ and have been keeping up with it for decades. It was the second language I learned in 1994 and I still code in it professionally today.

Like I pointed out with Matlab, it’s a much older language compared to c++ yet is mostly coherent, far more than c++. This has less to do about C++’s age and the March of time or the human condition. Otherwise more old languages would be as incoherent as c++ yet that’s not the case.
Please leave the personal attacks out of this, thanks. I've said nothing personally against you and yet you've turned to calling into question my profession rather than the points I've raised. I understand maybe it may feel like I'm attacking you personally as I'm criticizing a language which I gather you are very fond of, but criticizing C++ is not criticizing you, and I would appreciate if you show me the same respect I've shown you. That's not what this site is for, and if you want to engage in that kind of back and forth I'd kindly decline.
My students give me high marks, my department (which includes faculty who have contributed to C++ spec over the years) is satisfied with my teaching, and I graduate students that go on to work at top companies and research labs around the world. I'm doing my job just fine, let's stick to talking about C++.

This is the human condition.
