One of the slides in Blow's talk about why he was starting work on Jai said, "If we spend a lot of time wading through high-friction environments, we had better be sure that this is a net win. Empirically, it looks to me like [that] does not usually pay off. These methods spend more time preventing potential bugs than it would have taken to fix the actual bugs that happen."

I think that's an overall good summary of the crowd's attitude. They think that mainstream programming environments err too far in the direction of keeping your software from being buggy, charging programmers a heavy cost for it. Undoubtedly for videogames they are correct.

Jai in particular does support array bounds checking, but you can turn it on or off as a compilation option: https://jai.community/t/metaprogramming-build-options/151
