Comment on After outages, Amazon to make senior engineers sign off on AI-assisted changes
Aceticon@lemmy.dbzer0.com 2 weeks agoJust to add to this:
- When a senior dev reviews code from a more junior dev and gives feedback the more junior person (generally) learns from it.
- When a senior dev reviews code from an AI, the AI does not learn from it.
So beyond the first order effects you pointed out - the using of more time from more experience and hence expensive people - there is a second order effect due of loss of improvement in the making of code which is both persistent and cumulative with time: every review and feedback of the code from a junior dev reduces forever the future need for that, whilst every review and feedback of the code from an AI has no impact at all in need for it in the future.

Seniors reviewing code is fine but only when, as someone else mentioned, the code writer is learning from the review. The AI doesn’t learn at all and the Jr Dev probably learns very little because they didn’t understand the original code. Reviewing AI code often turns into me rewriting most of it.

Exactly.
The best way to learn is to have done the work yourself with all the mistakes that come from not knowing certain things, having wrong expectations or forgetting to account for certain situations, and then get feedback on your mistakes, especially if those giving the feedback know enough to understand the reasons behind the mistakes of the other person.
Another good way to learn is by looking through good quality work from somebody else, though it’s much less effective.
I suspect that getting feedback on work of “somebody” else (the AI) which isn’t even especially good yields, very little learning.
So linking back to my previous post, even though the AI process wastes a lot of time from a more senior person, not only will the AI (which did most of the implementation) not learn at all, but the junior dev that’s supposed to oversee and correct the AI will learn very little thus will improve very little. Meanwhile with the process that did not involve an AI, the same senior dev time expenditure will have taught the junior dev a lot more and since that’s the person doing most of the work yielded a lot more improvement next time around, reducing future expenditure of senior dev time.
