Who cares? Just like most things your average programmer relies on, they are written by smarter or at least more specialised people to make your job easier. They have learned to write memory-safe code so you don't have to.
I don't think those are the problem, but rather how they are used. And in case of managed languages like C#, it's almost impossible to shoot yourself in the foot when it comes to memory management. You still can, if you really wish, but you have to be very explicit in that. 🤷♂️
