It is absolutely necessary to move to higher levels of abstraction in order to handle the increasing complexity of modern programs.
And this is 100% right, but people should be educated about "premature abstraction". Have you seen the horrors of "generalization"?
Especially C++ neophytes get so excited by pointless generalization, then some grow out of it (studying other languages also helps) but some never do.
We write a lot about powerful techniques and neat applications, but often forget to show the perils and tradeoffs.
