Not saying you're wrong, but... do you have any source for saying that Julia has as many users as Rust?

On TIOBE, Julia (27) and Rust (20) are relatively close right now, and TIOBE might have some correlation to number of users. https://www.tiobe.com/tiobe-index/

TIOBE's methodology is a joke. I'm surprised it gets a mention on a forum like HN which tends to attract the sharpest minds in the industry.

We sure are all great on here aren’t we? Plaudits to everyone involved.

If you look at the IEEE top programming language list, it is still close. Believe it's Rust ranked #20 to Julia's rank of #28 (if my count is correct). https://spectrum.ieee.org/top-programming-languages-2022

And if you compare the IEEE to the TIOBE list, there appears to be a high degree of correlation. I think part of the criticism against TIOBE, is when people's favorite is not doing as well as they would like or a language they don't like is doing better than they expected.

The author of this tool commented below; Julia simply wasn't included in the list. Plugging it in gives it quite a high score compared to other languages (top ten in 2/3 categories).

Anecdotally, I feel like I see article "on" julia at least as often as rust on HN. I totally expected it to come "second" on most categories, and was very surprised not to see it there.

Then I realised that most julia articles would rarely introduce the julia component as "in Julia"; certaintly not in the same way that people tinkering with rust would be keen to report it as such. If anything I have noticed that most articles on Julia tend to be a bit backdoorish (i.e. the title is on, say, differentiation, but then you go to the article and it's basically an article about julia).

So I think it's just a side-effect of the methodology used to rank languages; not sure if it reflects actual market-share or the result of a vocal community engaging HN specifically, but julia definitely has a much stronger presence on HN than implied by this tool/article.
