How AI assistance impacts the formation of coding skills

I think this is where current senior engineers have an advantage, like I felt when I was a junior that the older guys had an advantage in understanding the low level stuff like assembly and hardware. But software keeps moving forward - my lack of time coding assembly by hand has never hindered my career. People will learn what they need to learn to be productive. When AI stops working in a given situation, people will learn the low level detail as they need to. When I was a junior I learned a couple of languages in depth, but everything since has been top down, learn-as-i-need to. I don't remember everything I've learned over 20 years software engineering, and the forgetting started way before my use of AI. It's true that conceptual understanding is necessary, but everyone's acting like all human coders are better than all AI's, and that is not the case. Poorly architected, spaghetti code existed way before LLM's.

An important aspect of this for professional programmers is that learning is not something that happens as a beginner, student or "junior" and then stops. The job is learning, and after 25 years of doing it I learn more per day than ever.

No surprise, really. You can use AI to explore new horizons or propose an initial sketch, but for anything larger than small changes - you must do a rewrite. Not just a review. An actual rewrite. AI can do well adding a function, but you can't vibe code an app and get smarter.

I don't necessarily think that writing more code means you get better coder. I automate nearly all my tests with AI and large chunk of bugfixing as well. I will regularly ask AI to propose an architecture or introduce a new pattern if I don't have a goal in my mind. But in these last 2 examples, I will always redesign the entire approach to be what I consider a better, cleaner interface. I don't recall AI ever getting that right, but must admit I asked AI in the first place cos I didn't know where to start.

If I had to summarize, I would say to let AI implement coding, but not API design/architecture. But at the same time, you can only get good at those by knowing what doesn't work and trying to find a better solution.

It's good that there's some research into this - to confirm what is generally obvious to anyone who studied anything. You have to think about what you are doing, write things by hand, use the skill to improve and retain it.

Common example here is learning a language. Say, you learn French or Spanish throughout your school years or on Duolingo. But unless you're lucky enough to be amazing with language skills, if you don't actually use it, you will hit a wall eventually. And similarly if you stop using language that you already know - it will slowly degrade over time.

Go Anthropic for transparency and commitment to science.

Personally, I’ve never been learning software development concepts faster—but that’s because I’ve been offloading actual development to other people for years.

> Unsurprisingly, participants in the No AI group encountered more errors. These included errors in syntax and in Trio concepts, the latter of which mapped directly to topics tested on the evaluation

I'm wondering if we could have the best of IDE/Editor features like LSP and LLMs working together. With an LSP syntax errors are a solved problem, if the language is statically typed I often find myself just checking out type signatures of library methods, simpler to me than asking an LLM. But I would love to have LLMs fixing your syntax and with types available or not, giving suggestions on how to best use the libraries given current context.

Cursor tab does that to some extent but it's not fool proof and it still feels too "statistical".

I'd love to have something deeply integrated with LSPs and IDE features, for example VSCode alone has the ability of suggesting imports, Cursor tries to complete them statistically but it often suggest the wrong import path. I'd like to have the twos working together.

Another example is renaming identifiers with F2, it is reliable and predictable, can't say the same when asking an agent doing that. On the other hand if the pattern isn't predictable, e.g. a migration where a 1 to 1 rename isn't enough, but needs to find a pattern, LLMs are just great. So I'd love to have an F2 feature augmented with LLMs capabilities

Another study from 2024 with similar findings: https://www.mdpi.com/2076-3417/14/10/4115 -- a bit more preliminary, but conducted with undergrad students still learning to program, so I expect the effect would be even more pronounced.

This similarly indicates that reliance on LLM correlates with degraded performance in critical problem-solving, coding and debugging skills. On the bright side, using LLMs as a supplementary learning aid (e.g. clarifying doubts) showed no negative impact on critical skills.

This is why I'm skeptical of people excited about "AI native" junior employees coming in and revamping the workplace. I haven't yet seen any evidence that AI can be effectively harnessed without some domain expertise, and I'm seeing mounting evidence that relying too much on it hinders building that expertise.

I think those who wish to become experts in a domain would willingly eschew using AI in their chosen discipline until they've "built the muscles."

Good to see that Anthropic is honest and open enough to publish a result with a mostly negative headline.

> Importantly, using AI assistance didn’t guarantee a lower score. How someone used AI influenced how much information they retained. The participants who showed stronger mastery used AI assistance not just to produce code but to build comprehension while doing so—whether by asking follow-up questions, requesting explanations, or posing conceptual questions while coding independently.

This might be cynically taken as cope, but it matches my own experience. A poor analogy until I find a better one: I don't do arithmetic in my head anymore, it's enough for me to know that 12038 x 912 is in the neighborhood of 10M, if the calculator gives me an answer much different from that then I know something went wrong. In the same way, I'm not writing many for loops by hand anymore but I know how the code works at a high level and how I want to change it.

(We're building Brokk to nudge users in this direction and not a magic "Claude take the wheel" button; link in bio.)

It makes sense - juniors are coding faster but not understanding anything. Ironically it'll stop them getting more experienced despite feeling good. What I'm interested in is if the same applies for Senior+ developers. The soft signals are that people are feeling the atrophy but who knows...
