I accidentally spoiled that part for my wife. I had already seen it several times before and was watching it again with her. She had her head on my chest and apparently my heart started beating faster at the ramp up to that part, so she knew what was about to happen and called it right before it happened.
I’d believe it’s real. In 2016 I was at a company trying to migrate off an old IBM mainframe and green screens. It wasn’t like an airline with complex or critical code; it was just a barely functional ERP for a warehouse. Source control was the furthest thing from their minds. Some companies and IT departments are very reluctant to change, regardless of how much time and money it save.
