Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Dealing with nested transducers ?
Maybe https://github.com/cgrand/xforms The for transducer might help, just as the for comprehension helps unpack and map/filter nested stuff.

What are some great Clojure libraries, as of 2021?
cgrand/xforms is a very useful hidden gem, if you like transducers/eager evaluation/solving map-vals without meander/specter.

Why Clojure?
* It's fast enough for 99% of apps out of the box. It's fast enough for 99.99% of the apps with minimal tuning.
* Yes, if your project is very big and macro heavy, it can take some time, but startup times have improved. In any case, I BARELY need to restart my development JVM. I have one currently running that I haven't restarted for 1 week+.
* Depending on what's your cup of tea, there's emacs/CIDER or IntelliJ/Cursive. They both work well. IntelliJ/Cursive is an excellent IDE combination. I use it every day.
* Java interop is very straightforward, not sure what you mean. Sure your code might not be all pure anymore, but that's the price for solving actual problems.
* Good java libraries have wrappers. A ton of original Clojure libraries as well. https://github.com/cgrand/xforms for example allows you to easily do things that I can't even imagine doing in an imperative language.
* Static vs dynamic typing: don't want to get into that.
* "Clojurescript isn't the same language". I use both Clojure and ClojureScript every day and as far as Clojure-only code is concerned, it works in both languages 99.99% of the time. One case you can encounter issues is if you do something host-specific, like dealing with numbers. That's by design. Clojure embraces each host, does not try to reinvent it. When you just use pure Clojure data structure manipulation, it works the same across both languages and works like magic.

What are the small reasons to try Emacs?
Some killer features in Emacs, which I would recommend checking out, is imenu and movement by s-expression (functions like forward-sexp). These are built into Emacs and make navigating across or inside blocks of code very easy. I have also seen that lispy, which is usually used for Lisp code also supports Python. Again I can't speak to any specifics about how well these things work for Python devs.

Any way to make lispy format works automatically?
While writing other programming languages with LSP, it formats the buffer once I hit save. Is there any way to make https://github.com/abo-abo/lispy do some equivalent behaviour?

Emacs/Slime equivalent of some Cider features?
I don't know cider, but...I found lispy mode a revelation in making the easy, easier.

Why is it hard to get started with elisp in emacs
The level of interactivity in your emacs determines how easy trying emacs-lisp becomes. I suggest checking out https://github.com/abo-abo/lispy, it makes it easy to look up documentation (C-c 1 I believe) and evaluate S-expressions on the fly (keybinding is e). Also C-h f, C-h k, C-h v are always very helpful. Also check out helpful (the package), selectrum, marginalia, prescient, etc.

Tree Sitter and the Complications of Parsing Languages
Emacs seems to attract quite a lot of people who want structural code editing. We now have * paredit * smartparens * evil-cleverparens * lispy * symex * combobulate (more?)

The State of Structural Editing in Emacs?
Obviously, we have packages like Paredit and Lispy, recently we got SymEx, but these are all for the Lisp family of languages, where syntactic redundancy is very high because of the homoiconicity.
What are some alternatives?
babashka - Native, fast starting Clojure interpreter for scripting
smartparens - Minor mode for Emacs that deals with parens pairs and tries to be smart about it.
clojure-dsl-resources - A curated list of Clojure resources for dealing with domain-specific languages.
parinfer-rust - A Rust port of parinfer.
meander - Tools for transparent data transformation
