In this case, a 'run-time failure' would be completely unacceptable, as the 'run-time' environment is your $X000 hardware manufacturing run. Hardware development isn't in the same league as software. It's not even the same sport. Like comparing football to rugby. Both played on a gridiron, but entirely differently.
First, there exist software environments where errors cost significantly more than a hardware run. Obviously, those environments contain hardware as well, but "cost of a runtime error" is clearly not the only important thing here.
Second, my only point was that the example given was a piss poor example of the difference between hardware and software. Obviously a bad example doesn't disprove the claim it's supposed to support.
Everyone's piling on you because that wasn't the point of the example. Automation grants humans extraordinary powers, as long as humans aren't simply steps within the automatic system.
There's been an awkward growing phase of the technology industry that has led to technicians that don't have any real understanding of the systems they maintain. Compare and contrast Robert DeNiro's character in Brazil with the repairmen he has to clean up after. We could be training those poor duct maintenance guys better.
