alt Hacker News> No one claims that good type systems prevent buggy software.
That's exactly what languages with advanced type systems claim. To be more precise, they claim to eliminate entire classes of bugs. So they reduce bugs, they don't eliminate them completely.

If you eliminate the odd integers from consideration, you've eliminated an entire class of integers. yet, the set of remaining integers is of the same size as the original.

No nulls, no nullability bombs.
Forcing devs to pre-fix/avoid bugs before the compiler will allow the app means the programs are more correct as a group.
Wrong, incomplete, insufficient, unhelpful, unimpressive, and dumb are all still very possible. But more correct than likely in looser systems.
