I’m not a developer, but when I watch devs whose work process is prompt, copy-paste, try to run, paste error into code, try to run, etc. I can’t help but think they’re unskilled. There’s no brain engagement, no understanding of the bigger picture, just being a worse slower agent.

Sure, but even worse, is the state-of-the-art: they use a cli agent and the "copy-paste, try to run, paste error, try to run" loop is called "Agentic engineering." Now we have to believe they're 10/10?

I see no difference there except speed at the cost of whatever little understanding may have been gained by the manual inspection between steps.
