Some people would rather that proper coders actually built something that worked properly, rather than having to do the fucking job yourself. (If that means allowing for user-configurable UI, then that's probably fine. But most people want to do their job without having to learn a complete new family of skills.
I asked the welder to build me a bracket last night. He built it. He didn't need to program the nearest CNC machine (120km away) to have it manufactured then shipped to location (3-4 days, plus paperwork). Instead he made me the bracket, dunked it in a bucket to cool the welds off, and passed it to me. He doesn't need to code, and it's unlikely that he ever will need to.
