In the old days we programmed systems by literally wiring them. There wasn't much work, only a few "programmers" were employed. Then somebody came up with Punch cards that was much more vision than wiring the systems directly. This opened the door for a lot more people to use them and now programmers were busier.
The punch cards didn't scale either so eventually we created panels with buttons so we could type the programs into the computers. That was more efficient and now all the sudden it lowered the bar entry and more people who are employed and doing the work.
Assembly language to machine code compilers to assembly language high-level languages and LLMs.
Every time developing software gets easier, it only increases the amount of work required. I'm busier today than I've ever been in my entire life.
What's going to happen to software engineers? They're going to be overworked and they're going to be given more work and the cycle will never end.
