How AI Impacts Skill Formation

Abstract
AI assistance produces significant productivity gains across professional domains, particularly for
novice workers. Yet how this assistance affects the development of skills required to effectively supervise
AI remains unclear. Novice workers who rely heavily on AI to complete unfamiliar tasks may compromise
their own skill acquisition in the process. We conduct randomized experiments to study how developers
gained mastery of a new asynchronous programming library with and without the assistance of AI.
We find that AI use impairs conceptual understanding, code reading, and debugging abilities, without
delivering significant efficiency gains on average. Participants who fully delegated coding tasks showed
some productivity improvements, but at the cost of learning the library. We identify six distinct AI
interaction patterns, three of which involve cognitive engagement and preserve learning outcomes even
when participants receive AI assistance. Our findings suggest that AI-enhanced productivity is not a
shortcut to competence and AI assistance should be carefully adopted into workflows to preserve skill
formation – particularly in safety-critical domains.
Interesting paper, especially interesting it's coming from researchers at Anthropic arxiv.org/pdf/2601.20245

Ok, how about this happens at the Minneapolis Orchestra Hall, instead?

This must be weird news to see if you’re one of the literally hundreds or even thousands of university administrators who preemptively censored faculty, scrubbed websites, changed the names of centers, etc.

With AI having such an influence on grant writing now, I find it harder and harder to justify the way things are done now

How do you think you’ll feel when the paramilitary drives by your kid’s elementary school in a show of force? I hope you never have to find out.

Great to hear! I suppose I should have used a more pointed word than "considered"

Really surprising it's taken this long to consider doing this. The parkways have become a huge problem with mile long lines of motorists using it as a commuting "cut through", which it's clearly not designed for

Paul was such an incredible person. He made time for everyone. He was patient, humble, and so so supportive. I'm so sad to hear he's gone

By the end of the spring semester, Gwen reached a breaking point with AI. “I felt like I didn’t deserve to be a Yale student,” she said. She thought that she was throwing away her education and the scholarship paying to support it.
She decided to quit using ChatGPT altogether. She didn’t ask AI to help her sentences flow or to strike the right tone. She didn’t even use it to brainstorm. “I think that’s a skill you need to have on your own. That’s the core of being original, anyway.”
Gwen recalled completing her final assignments without AI, sitting in the middle of a crowded library so that she felt watched. “I struggled. And they weren’t very good.”
It was only then, she said, that she started to understand just how much learning she had missed out on. ∎

That’s the other thing that baffles me about AI and creative writing, actually.
The work IS the joy for me. I don’t want to be able to snap my fingers and have a completed “product.” I want to be transformed by the process. I’m an author but I do this because I enjoy the rigor of being a writer.

A lot of people invoke "ML" when they're not doing ML. That doesn't make ML bad

this isn't causal inference, this is just people being lazy/doing stupid stuff

Also debugging code you don't fully understand the "logic" behind takes much longer than debugging something you thought carefully about and made yourself

Would like to see the details of this study, but this does track with my experience -- AI is likely not helping you as much as you think it is even for basic things like coding

I absolutely think that for the majority of users it definitely is a crutch to replace critical thinking. It *can* be used without that being the case, but it most often seems not to be
