I complained also about the "cowboy" culture I saw among the Julia developers when I first started with it (people making a change directly to master, or merging there own PR without giving time for people around the world to review, or not having a minimum number of qualified reviewers before merging), but those days are gone, and I feel they've matured quite a lot in the past few years in that respect. Some of it I think was simply the great excitement that comes from being able to be so creative with the language, and a rush to get things figured out and nailed down to finally get to v1.0. As far as projects in other languages, I don't really feel it has much to do with the languages themselves, more the type of people that particular project attracts.

Just in the last few months BinDeps was broken by a "deprecation fix" that was completely wrong and using a name that didn't exist, and it got merged and released by the patch author before anyone else could look at it, breaking many downstream packages.

Refactorings and major changes in ZMQ.jl and the web stack similarly get merged and released immediately with zero review, still. This is a major problem.

Features in the base language have been deleted during 0.7-DEV because a single core developer didn't like them, despite multiple other core developers voicing disagreement that the features were useful and removing them was not urgent or necessary.

It's not a development culture I would rely on when products and money and jobs are at stake. Even the startup you were working with abandoned julia, correct?

What I don't understand is why you didn't just stay with old stable versions? You wouldn't be exposed to such issues, wouldn't you?

On the other hand this 'development culture' has brought brilliant results in a relatively short amount of time with a relatively small team.

There was a talk [1] at the Juliacon 2018 where a company very successfully replaced an IBM product with Julia code. At 48:07 there was a question 'about problems with changes in Julia'. Answer: they started with v0.3 and 'didn't really have many problems'. They 'didn't use anything particularly exotic'. So, yes, I'd say if you adapt to the given situation it can (could have) work(ed).

I'm not convinced that a non-cowboy style would have been better. (And besides, this doesn't come free moneywise).

These incidents were with respect to 0.6-supporting versions of packages. Pinning is a good idea for reproducability but it's not the default, so updating packages or new installs are broken when careless things make it instantly into a release.

Talk to me when google, amazon, microsoft, facebook etc are publicly using and officially supporting julia on cloud platforms or even infrastructure libraries like protobuf.

The carelessness isn't responsible for or helping anything. A good diffeq and optimization suite have been built despite the prevalence of careless practices, not because of them.

It's not a question of money either, just patience and code review and recognition of how many things downstream are going to be affected by mistakes. You'll save more time in not having to put out as many fires than it will cost to slow down and not be in such a rush at all times.

I was not expecting the change to MDD (Marketing Driven Development) at the last minute. But at least 1.0 is out, I hope those wild west times, get past far behind us now. I'll wait for Julia 1.1 and most packages at 1.0 before diving back in.
