I forget where I read that there were estimated to be only about 1K professional Erlang coders in the world. That seems absurdly low. Does anyone believe this is actually true?
Incorrect, it probably got confused with the number of Erlang developers at Ericsson. Not all use it on a daily basis, but estimates on their developers, testers and system integrators is in that range.
That's what people used to think of Symbolics Lisp machines. Customers would assume Symbolics had a team of thousands of programmers, when really it was about a dozen.
