You of course have a point in that "you can't argue with taste".

However programming languages live and die by the size of their community. Erlang has, by choice of an over-brewed and bitter syntax, drawn itself into a niche much smaller than it deserves. The only chance to escape would be to adapt a more popular taste.

Otherwise it will eventually be obsoleted by a language "as powerful as erlang, but minus the arcane syntax".
