My point is: these are all individual attempts (the book i mean) and there will always be something on page xyz broken and it can't be solved by individuals. To solve these problems, there needs to be constant time and money investment from someone serious (like facebook in case of create-elm-app).
There is some community effort to better fund the core infrastructure in Clojure through https://www.clojuriststogether.org/, hopefully they can continue to attract more funding developers and companies.
In general a lot of these issues could be alleviated if the community was just in general larger with more contributors. I think the Clojure community is quite welcoming to newbies in the sense that people are quite responsive, kind and helpful around the internet, in Clojurians Slack (try asking there btw, if you haven't yet and are still stuck at the start of the book), etc. But in other ways people seem averse to criticism or suggestions from outsiders. I think the Clojure world needs to do a bit of self reflection to understand why adoption is so low right now and honestly consider what needs to change to attract more developers and contributors.
