Because humans were, loosely speaking, careful about not making egregious security mistakes, most security vulnerabilities turned out to be either harmless or the result of a programming language allowing the type of exploit to begin with.
But now we have code from non-people ordered by people who both don't care about security at all.
That means you will get maximally bad security outcomes which in turn will make governments consider regulating the software development industry. They are speed running their own demise.
