Abstraction is clearly fundamental to computer science. It is also *really hard* to do well, and is frequently done poorly. I honestly don't think I am smart enough to use many C++ abstractions well, so I stick with more C-style code.

Part of the design of C++ is that you don't have to use those things, though. You are supposed to be able to 'open the hood' and take control back where necessary. It is arguable how well this works.
The issue is when a useful 3rd party library opts into those abstractions and forces you along with it.
