IIRC the damage done by software bugs to US economy alone is

Interesting. Source? :)

Eg. here:

I think many other studies estimate the cost to be higher.
Nobody is doubting the high cost of software bugs. The doubt here is that null
pointers are far and away the most common source of bugs (and I mean source, not
just the symptom).
The only way to resolve this would be to to go through the bug databases of
resolved bugs and their fixes and actually count which ones were due to a null
pointer that would have been caught by nonnull types.
