Thomas did not say that the ADT is no longer relevant, he just said
that the big buzz about their use has died back a bit as people
realised that it doesn't solve all of their problems.  As is normal
there is no one general solution to every problem.

Nothing.  The concept is still there and useful (and before you claim
that I said it was a buzz word, I said that because it seemed you were
using it like one.  That is I agree with Thomas, ADTs are not
something to organize all our thoughts around.).

As I said above, you misinterpreted his words (afiak) by taking them
too far.
