Programming is more like trades than you think. A bad plumber might occasionally cause a flood, just like a bad programmer might occasionally cause a hard crash during an important sales presentation, but actually bad plumbers use sub par material, and install them incorrectly, and you don't know until 5 years later when your first floor is flooding because a pipe joint inside the wall finally burst after the 1000th time water hammer slammed it. And, like programming, sometimes you'd find someone who actually just didn't know what they were doing because they were inexperienced, and sometimes you'd find someone who was rushed and underfunded, but in either case they are generally long gone, and the cause of the ultimate failure isn't perfectly clear, so the world turns and everyone keeps plumbing, for better or worse. I can tell a similar story for almost all trades.
