Julia is a nice language, it's just tough to compete with Python.
- The beginner experience in Julia is still much worse than it is in Python. Stuff that should work intuitively sometimes doesn't, and when you get a cryptic error message, it's difficult to find relevant help online. And when you do find help, some of it is out of date because the language has changed over the past few years.
- You can squeeze a lot of performance out of Python and the ecosystem of libraries is hard to beat.
- Julia has to be way better than Python to give people an incentive to switch. Being just marginally better in some aspects of the language isn't enough. And it's very difficult to be much better than Python especially in useability and ecosystem.
