Hell, if you wait long enough, they'll just deprecate it before you can care to bother.
But if you work with C++ in professional context, you will encounter it somewhere (library, teamate's PR, legacy code, LLM output, book / blog / conference ...). |
You actually need to know the bad stuff to be able to judge it and discard it.
Im talking about your own personal coding. You dont have to use the new things. You dont have to know them to decide to discard them. In fact, the criteria to discard something is to not know it. You generally shouldn't be using things you dont know anyway.
The fact that other people use things you do not know is not a reason to stress out about the dumb pace and direction c++ is moving in. It is possible to enjoy a life free from fomo about the c++ standards goalposts.
