While automated reasoning tech is getting better, the barriers have been more on the demand side. Until buggy vulnerable software makes you poor and visibly correct software makes you rich, we'll keep getting the vulnerable sort. IOTA, which rolled their own hash function and then blustered about the problem, right now has a market value of ten billion dollars.
We're starting to see a change in the economics. There's quite a way to go -- I hope we get there intelligently and not as some kind of thrashing reaction to giant disasters.
