This is quite a good intro: https://viralinstruction.com/posts/badjulia/

fyi: the author of that post is a current Julia user and intended the post as counterpoint to their normally enthusiastic endorsements. so while it is a good intro to some of the shortfalls of the language, I'm not sure the author would agree that Julia has "failed" due to these details

Yes, but it's a good list of the major problems, and laudable for a self-professed "stan" to be upfront about them.

It's my assesment that the problems listed in there are a cause why Julia will not take off and we're largely stuck with Python for the foreseeable future.

It is worth noting that the first of the reasons presented is significantly improved in Julia 1.9 and 1.10 (released ~8 months and ~1 month ago). The time for `using BioSequences, FASTX` on 1.10 is down to 0.14 seconds on my computer (from 0.62 seconds on 1.8 when the blog post was published).

TTFX is indeed getting a lot better. But e.g. "using DynamicalSystems" is still over 5 seconds.

There is something big going on in caching the binaries, so there's a chance the TTFX will get workable.
