Unfortunately, in some languages, inheritance of abstract classes is the only way to get the equivalent of interfaces.
That said, yeah, the less class inheritance, the better. Ideally, work in a language where interfaces can include default implementations.

Totally, no problem with default implementations as long as they are generic. Java finally supports this, as well as Rust and others.

c++ is a great language but a lot of the inheritance system is regrettable at best.
edit: It's worth the down votes on this. Multiple inheritance is pure evil and confusion. In fact, even in Java I now rely on aggregation over inheritance.
