@Felthry bet the reason is that it's a) old and b) parallelizing code is hard
@noiob probably. i'm just complaining, mostly! I think there's some parallelization stuff you can do but you have to both explicitly design your model around that, and buy their multi-threading package to do it (which is another problem but bleh)
@Felthry ah, so they're basically handing the complexity over to the user
