At the end of the day I think it's just a matter of cost. If it's cheaper to let a software fail and simply fix it when it does, there will not be much interest into proving it to be correct. If a failure will likely be vastly more expensive than proving correctness, then proving correctness will make sense. There are simply way less instances of the second category. I think one of the few "new" instances, which might be worth mentioning is smart contract programming, where failures can cause millions of loss and proving correctness is not too expensive.
