I believe that FPLs provide companies with a competitive advantage that can be used to out-compete companies using non FPLs. But life is not simple, in order to turn our ideas into money we can't just go and explain our latest fancy type systems to a venture capitalist and expect money to rain out of the sky - we have to do a lot more things.
In my talk, I'll talk about the "other things" that have to be done to get FP established and to earn money from the technology.
Spoiler: The 19$B WhatsApp acquisition by Facebook shows that not only can FP ideas earn money - but actually earn more money than in any other acquisition to date (WhatsApp messaging is programmed in Erlang :-)
