You just need to know what you're doing The problem is that there just aren't that many people who choose to invest in learning Haskell -- or for that matter, the essential-to-master nooks and crannies of Rust. And the learning curve to get there is intrinsically steeper that for, well, all those "dum-dum" ducktyped and/or mostly procedural languages one imagines you don't particular care much for, now do you. Of cou…
How do you know it didn’t work out very well for them and they keep it quiet just so the competion doesn’t gain the same advantage? There is that possibility or it could be that the same team would be capable enough to change the stack and paradigm and get more or less the same results, with some twist and a different flavor. It’s hard to know for sure I think.

Which, ironically, makes one further question whether it has all that much benefit. Because if it really did ... yeah, they'd probably want to keep quiet about it. Like any other truly winning strategy in their arsenal.
