I said "all USEFUL programming languages", thereby excluding toys, 
research projects, etc.

Of course, "useful" is a slippery concept, but a good proxy is having 
widespread adoption.

There are good reasons why Detroit's "concept cars" never survived 
intact into production. And why the windscreen on an airliner is flat 
instead of curved like the rest of the exterior.
