I believe that the part of the programming world that *requires*
error-free software knows how to produce that kind of software. The rest
of the world is happy with having ways to diagnose errors when they do
crop up, and fail-fast ("panic") approaches are a well-established way
of doing that.

That's how it works in the life-critical software business. You can't
leave that sort of thing up to off-the-shelf parts.
