The point was they trained to be a runner, not a cyclist.

But the metaphorical goal is to cover distance not get fit or to make the best use of what you trained for. A trained runner on a bike is faster than a trained runner.

At least if the metaphor is about coding as a means to creating usefully functional code as efficiently as possible. Careful coding by hand may eventually be a hobby activity.

Personally, while I do get some satisfaction in coding by hand it was always the production of something useful that I found most rewarding. I was never someone who wrote code for a hobby. With LLM's I'm more productive. And I find that very satisfying.
