> When you've lived with AI boosting your productivity for a year or more it's pretty easy to believe your own experience over even a well-constructed "randomised controlled trial".

Me: The person above literally pitches an unsupported belief against a study

You: it's pretty easy to believe your own experience over even a well-constructed "randomised controlled trial".

Really? Really?!!

As for "boosting your productivity", it's also what I'm talking about in the article I linked:

--- start quote ---

For every description of how LLMs work or don't work we know only some, but not all of the following:

- Do we know which projects people work on? No

- Do we know which codebases (greenfield, mature, proprietary etc.) people work on? No

- Do we know the level of expertise the people have? No. Is the expertise in the same domain, codebase, language that they apply LLMs to? We don't know.

- How much additional work did they have reviewing, fixing, deploying, finishing etc.? We don't know.

Even if you have one person describing all of the above, you will not be able to compare their experience to anyone else's because you have no idea what others answer for any of those bullet points.

--- end quote ---

So what happens when we actually control and measure those variables?

Wait, don't answer: "no, it's easier to believe yourself over a study".

See? Skeptics don't even have to "jump on anything that supports their skepticism." Even you supply them with material.

I'm not disputing that different people have radically different experiences of how much productivity boost they can get out of working with LLMs.

I've been banging this drum for over a year now: LLMs are deceptively difficult and uninituitive to use. Just one example: https://simonwillison.net/2025/Mar/11/using-llms-for-code/

What I'm willing to assert as fact, based not just on my own experiences (though they're a major role) but on observing this space for several years and talking to literally hundreds of people, is that LLMs can provide you a very real productivity boost in coding if you take the time to learn how to use them - or if you get lucky and chance upon the most productive patterns.

EDIT: I just saw you're the author of https://dmitriid.com/#everything-around-llms-is-still-magica... - that was a great piece! I think I may actually agree with you. I misinterpreted "magical thinking" as referring to something else.

> that was a great piece!

Thank you!

> I think I may actually agree with you.

I was just going to write "see, you actually agree with me", but got hit by the reply rate limit :)

And I agree with >90% of what you write, so I was surprised that this bout took us to weird places.
