For example, picking the first question I can see on discourse (which isn't a clear technical question, it was number 3) is "What is the status of debugger?". The first answer is "I've used Julia for 3 years and I don't need a debugger" whereas searching for similar questions on the Rust discourse tends to find answers.
This isn't a complete investigation, it might just be me generalising from my small number of interactions with the Julia and Rust communities.
Your post gives the impression that the question was dismissed, maybe even giving the impression that there is no work on a debugger, which is quite misleading. There are several debuggers, and lots of work.
There is some controversy in the community about the _need_ for a debugger, with people with strong opinions on both sides.
As for the general tone, I don't know what to say, except that I find it quite helpful, with lots of people putting in a lot of effort to help whomsoever comes along with questions.
I routinely point people to the Julia Computing case studies for this reason: https://juliacomputing.com/case-studies/
We also request people to please file an issue against Julia or a package if it doesn't do what you expect it to, or post on discourse. That way, even though you may go ahead with a different tool, someone is likely to fix it by the time you come back the next time. :-)
