Abstraction considered harmful

From SICP:

We control complexity by building abstractions that hide details when appropriate

Which means that with abstraction the whole system will grow and bloat without the programmer noticing it.

Abstraction in practice is too heavily tied to black boxes.  Building things up in layers is fine, but not letting programmers look at what inside the layer below is not.  Just because the code doesn't need to know the implementation details doesn't mean I don't.
