So are you saying that code quality is not critical elsewhere ? I agree in general that many companies have shitty code but there are many places which actually do care about code quality and code reviews are actually important.

He's saying safety-critical. Like NASA software. As in, if the code hits an NPE or array out-of-bounds or int overflow, people die. They actually use formal methods which is an exhaustive testing of every possible state the program could possibly enter.

We don't do this for business applications because it's extraordinarily expensive--can cost $100's per LoC.

And yeah, I think the several times daily I see "Microsoft Excel has encountered a problem and needs to close" is evidence that most major software shops have very poor quality control.
