This seems like a weird way to look at the problem. Hardware also has software/logic. The only reason it appears more stable is that people are shit scared of finding a bug that can't be fixed. If we delay the software release as long as a hardware development takes, with corresponding QA, I don't see why switching it all to hardware is going to make any more sense. Immutability is all it has, unless you are somehow implying that one can be hacked (by bad actors) and the other can't be.
