I also think it's the future, the problem is that I don't believe that Dyalog APL is the future, even though it's really nice. It just should be opensource to succeed imho., why still be so greedy and take money for a language. Also the IDE is really weird. I love APL and J, but I think there is a lot of space for improvement. And I want that improvement to happen in the open. They can still charge for Consulting, Hosting whatnot.
