So 70% of the vulnerabilities are still caused by lack of memory-safety, and that doesn't even account for all the defects that don't end up in a vulnerability.

So 70% of the vulnerabilities are still caused by lack of memory-safety, and that doesn't even account for all the defects that don't end up in a vulnerability. Imagine how much more safety and correctness there would be, if not only those 70% didn't exist, but no time had to be spent to fix them and rather concentrate onto avoiding the other 30%.
