Tbf, they the engineers I’m referencing right design The rockets but rather the test stands. They were used to things like manually actuated valves, analog data collection etc. In their world, they could have came up in industry with little to no software. Even after adoption, they thought software testing was a waste of time because “it’s just software, it doesn’t break.” Obviously, they were thinking as a mechanical engineer where “breaking” is synonymous with “wearing out” or “physically breaking”.
