Actually, both Unix and Ada are products of the 1970's.  The difference
is that Unix, being primarily of commercial interest, has been able to
evolve, whereas Ada, a government sponsored thing-a-ma-bob, has
stagnated.  It's a shrine to the ideas of 1975, both good and bad.  The
fact that Unix has evolved in ways incompatible with Ada says as at
least as much about Ada as it does about Unix.

I followed the development of Ada from its inception as Strawman, and
became increasingly more depressed as the work proceeded.  The good
concepts Ada embodies are overwhelmed by its complexity (see Hoare's
excellent discussion of this in his Turing Lecture -- all of his
comments still apply).

Ada is the PL/I of the 70's, unusable until the mid-80's; is it destined
to be the choke-collar of DoD software development in the 90's?

Now, if Unix has been able to evolve why hasn't it done that? It
still looks like a remnant from the sixties to me.
