Everything can be theoretically be safe if you just do X and Y, but very often the economical incentives are to avoid doing X and Y (mostly to reduce expenses)

Everything can be theoretically be safe if you just do X and Y, but very often the economical incentives are to avoid doing X and Y (mostly to reduce expenses) so if you don't have safety as a complete stopper (as in: program does not compile if you don't abide by safety) then programs will be unsafe until the end of time. We have to stop the problem at the door, not let it in and try to pacify it after it has destroyed half the room. What a nonsensical article. I mean yeah, guns with the safety off are perfectly safe if 100% of all users have perfect trigger discipline, right?
