Bad engineers continue being bad, good engineers continue being good.
I personally don’t know any colleagues who were good engineers just because they wrote code faster. The best engineers I know were ones who drew on experience and careful consideration and shared critical insights with their team that steered the direction of the system positively.

Same, if anything, the opposite seems to be true, the ones that I'd call "good engineers" were slower, less panicked when production was down and could reason their way (slowly) through pretty much anything thrown at them.
Opposite experience, I've sit next to developers who are trying their fastest to restore production and then making more mistakes to make it even worse, or developers who rush through the first implementation idea they had for a feature, missing to consider so many things and so on.

Unfortunately, a lot of workplaces are ignoring this, believing their engineers are assembly line workers, and the ones who complete 10 widgets per minute are simply better than the ones who complete 5 widgets per minute.
It isn't just that they believe this - they want a business model where this is how it works. For a big company a star coder is a liability - they have strong labor power, they can leave and they are hard to replace, etc.
Companies want workflows that work with mediocre programmers because they are more like interchangeable parts. This is the real secret to why AI programming will work in a lot of places. If you look at the externalities of employing talented people, shitty code actually looks better than great code.

However, the best engineers I know are usually among the quickest to open an editor or debugger and use it fluently to try something out. It's precisely that speed that enables a process like "let's try X, hmm, how about Y, no... ok, Z is nice; ok team, here are the tradeoffs...". Then they remember their experience with X, Y, and Z, and use it to shape their thinking going forward.
Meanwhile, other engineers have gotten X to finally mostly work and are invested in shipping it because they just want to be done. In my experience, this is how a lot of coding agents seem to act.
It's not obvious to me how to apply the expert loop to agentic coding. Of course you can ask your agent to try several different things and pick the best, or ask it to recommend architectural improvements that would make a given change easier...
Or: depth-first search of the solution space vs breadth-first (or balanced) search of the solution space.

The ideal solution increasingly seems to be encoding everything that differentiates a good engineer from a bad engineer into your prompt.
But at that point the LLM isn’t really the model as much as the medium. And I have some doubts that LLMs are the ideal medium for encoding expertise.

The Pragmatic Programmer book has whole chapters about this. Ultimately, you either solve the problem analogously (whiteboard, deep thinking on a sofa). Or you got fast as trying out stuff AND keeping the good bits.
