I'm glad I'm not the only one that feels this way. I love Julia as a language (not as an implementation, which is a pain-in-the-ass to work with), but there has long been a pattern of responses which in practice amount to gaslighting. Afaik it's only small set of people who do that, and charitably they're likely just being less-than-thoughtful about generalizing their "work for my project", "works on my 24 core computer", "works when I know half the people developing packages" experiences to everyone. But to an outsider, it looks like the answer is always "the problems are all fixed now, you're just out of date", and most of the time that turns out not to be true.
More than half the community feels that way the other half are either sycophants or don't care. It's not like it's one person either, it's the language maintainers general attitude. It's been called out in the past but it sure hasn't changed because there's a product to sell.
