I came to say the same thing! There is a hidden economy of programmers who often don't realize they're programmers. They're hidden inside every industrial facility, maintaining machines that use ladder logic to control their functionality in PLCs. And the ones I've met are generally brilliant at it. I was watching as one such person modify the program running a machine. "How do you deploy the change?" I asked. "Deploy? No, this is live. Every change I make is happening immediately."
