The problem with C++ is it still allows a lot of unsafe ways of working with memory that previous projects used and people still use now.

Why do you think this is a problem? We have a tool that gives everyone the freedom to manage resources the way it suits their own needs. It even went as far as explicitly supporting garbage collectors right up to C++23. Some frameworks adopted and enforced their own memory management systems, such as Qt.

Tell me, exactly why do you think this is a problem?

All the use after free and buffer overflow bugs that plague our key infrastructure.

It's not just that. Debugging segfaults and UB can be an absolute nightmare.

The C++ committee still haven't learnt their lesson. I recently learnt about C++20 coroutines, which are pretty neat, if complex (there are pretty much no good learning resources about them). However they are still putting unnecessary UB footguns in it.

Reminds me of how I found some safety measures to be in China some years back, basically those were signs saying "plz don't fall to your death, if you do it's your fault"

At least it's not like Russia, where it's “plz don’t fall to your death, if you do it’s our fault”...

I thought a lot of places are like that, that's why we get all the fences and such 🤔

Maybe a "pragma strict" where every deprecated is an error and not a warning?
