Or you know, maybe they have different view on these things.
There are good programmers out there who don't use RAII or smart pointers and think that most of this modern stuff is just added cruft for little gain.
Standard containers are nice but if performance is your problem you often need to re-implement them anyway and if it is not then maybe you could have done it in the higher level language in the first place.
Whatever float your boat (and your particular niche).
