Since those are only 2 options, and there are many more options, I'll pick option 3: convince people to value and fund universal education more from preschool on, building a better foundation for engineers and other professions in the decades following.
In addition to that, it'd be cool if the blameless postmortems were made public, so everyone could learn from them.
As for the other 2 options of restricting freedom, and extremely blameful postmortems, I reject both.
