Because I believe safety critical places like aviation are the ones that actually get things right. You can't pile on every demand on the human in charge and expect improvement. We're just not great at taking every possible detail into account. Doing lots of grunt work all the time reliably is what we have computers for.

In my old age, I find the more permissive a language is, the more painful it is to code in long term. Perl is great for simple things, but C++ was a vast improvement because it catches a lot of nonsense that Perl will compile just fine.

And debugging is so expensive that eventually writing code fast is near worthless. Whatever you gain you more than pay for in debugging afterwards.

C++ unfortunately doesn't go far enough.
