Many game programmers decided long ago that object-orientedism is snake oil, because that kind of abstraction does not cleanly factor a lot of the big problems we have.

There isn't anything close to unanimous agreement, but the dominant view is that something like single inheritance is a useful tool to have in your language. But all the high-end OO philosophy stuff is flat-out held in distaste by the majority of high-end engine programmers. (In many cases because they bought into it and tried it and it made a big mess.)
