Wow.I read the article when it first came out. Periodically, it gets re-posted.
My take on the article now is still what I thought then.
When hiring a team of SW engineers to build something, it
is critical to choose a language that a large number of
potential candidates know - "know" as in have already written
tens of thousands of line of; Concurrent Euclid might be
a great language (dating me) but the pool of engineers who
really know it is vanishing small.
