While I completely understand where this sense comes from, I think it’s a bit unfair to compare given the existing size and inertia of those other languages.
In my experience, having taught beginners in both python and julia and to a lesser degree R, that none of these languages is easier than the other. They all of pain points, and they all have conveniences. Actually, I find Julia much easier to teach, since I have to do way less “just ignore the why here…”, but if I’m being honest, students struggle in similar ways.
In truth, python, Julia, and R are good enough for almost all users, and the reality is that most scientists are too busy with non-coding stuff that they are not going to take the time to rigorously evaluate what is “best”, and will just do what the people around them do. And this is fine.
I do think threads like this are valuable as long as they stay respectful (which this one has), but the truth is, must of these points are known, and are either not directly solvable (we can’t magic a giant ecosystem into existence) or are being actively worked on and making strides (reducing TTFX) or have potential solutions/hacks, but aren’t high the highest priority (static binaries).
There are plenty of us that find Julia extremely productive. Some folks are making libraries that are better than any existing in any other language (eg the whole DiffEq ecosystem). As more scientists focus on Julia, or make things that are indispensable, or train their trainees in julia, more users will come.
In my field (biology) perl was completely dominant for a long time. There were arguments about python when it came on the scene that it would never rival perl, but we can see how that turned out (there are still bioinformaticians, most in their 60s, that still argue for perl, but their influence is waning).
Time will tell if Julia comes to displace other languages, or remains a small niche, or goes a different way. For now, use Julia if you like it, contribute if you can, and always feel welcome to share your thoughts or ask questions
