It's been a skill issue for 40 years. How long are we going to continue searching for those programmers who don't make mistakes?
Programmers make stupid mistakes in the safest languages too, even more so today when software is a career and not a hobby. What does it matter if the memory allocation is safe when the programmer exposes all user sessions to the internet because reading Dockers' documentation is too much work? Even Github did a variant of this with all their resources.
