What is wrong with this line of thinking? Why isn't it obvious that F# is going to be huge?
You're assuming the large masses actually write programs that need multicore support - or the programs would gain significant benefit from being parallellized. That's a false assumption.
Server side there's even less need for a parallell language.
Backend server processing already takes enough advantage of multicore/processor support by it's inherent nature of being concurrent(work is divided on clients via threads and among processes(e.g. one app server, one db server, one web container.. ).
