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.

Why does Racket have Type-Maps instead of Just a Single Map?
See related post. The dot operator in Rhombus will allow a function call like expr.map(…) to be statically specialized to Some.map(expr, …) provided that expr carries sufficient static information. This isn’t possible in Racket given the lack of static information in general.

Rhombus-in-the-rough: A 2D RPG implemented in the Rhombus Racket dialect
If you want to know more the best starting point is https://github.com/racket/rhombus-prototype They have discussion on the GitHub repo

Multiple namespaces?
Racket has the concept of binding space built on top of the scope-set model. The experiment language Rhombus makes heavy use of this for contextual bindings. Note that bindings are used for language extensions among other purposes in Racket.

Generalized and first-class macros: what is this called?
The notion of “tail sequence” in general doesn’t exist in Lisp’s macro-expansion model, since Lisp macros are strictly local transformations. A “tail sequence” allows a macro to control the expansion of the whole context, which requires wrapping the whole context in another macro in Lisp’s model. This is what leads to proposals like #%local-definition in Racket. However, this notion does exist in the enforestation model, which is what the experiment language Rhombus is based on, although it’s probably not quite a Lisp ;)

Anyone else concerned that Rhombus/Racket2 is not a lisp based language?
Rhombus is: - just another #lang. It is built on top of the existing Racket VM and written in Racket. It interoperates with existing Racket code and uses the Racket expander. - macro extendable. Hygiene and all of the good stuff work. - being developed in the open. We meet biweekly over Zoom, and discussions also occur in GitHub Discussions.
- Anyone aware of Racket projects that are in need of contributors? I am experienced in PL design and have two months worth of spare time. I have never contributed to an opensource project before besides taureg.

Racket->Rhombus: To Sexp or not to Sexp?
Querying Git references for rhombus-prototype at https://github.com/racket/rhombus-prototype.git Using cached16617263581661726358301 for https://github.com/racket/rhombus-prototype.git DrRacket install: version mismatch for dependency for package: https://github.com/racket/rhombus-prototype.git mismatch packages: base (have 8.6, need 8.6.0.9)
Instead of hoping, you might consider reading the discussions to see what the developers are actually saying. Just a thought.

The Loudest Lisp Program
Have you seen https://stevelosh.com/blog/2018/08/a-road-to-common-lisp/ ? "Kludges" everywhere is applicable. On the other hand, having a function like "row-major-aref" that allows accessing any multi-dimensional array as if it were one dimensional is "sweeter than the honeycomb".
I still think CL code can be beautiful. Norvig's in PAIP https://github.com/norvig/paip-lisp is nice.
As for the inside-out remark, while technically you do it, you don't have to, and it's very convenient to not do. Clojure has its semi-famous arrow macro that lets you write things in a more sequential style, it exists in CL too, and there's always the venerable let* binding. e.g. 3 options:
(loop (print (eval (read))))

The Meeting of the Minds That Launched AI
Emacs is so much more than a text editor! But I need to stay on topic...
I believe your assessment of LISP (and therefore of MacArthy)'s impact on AI to be unfair. Just a few days ago https://github.com/norvig/paip-lisp was discussed on this site, for example.

Towards a New SymPy
Sounds like a great project idea to make a toy demo of this direction you'd like to see. Maybe comparable to https://github.com/norvig/paip-lisp/blob/main/docs/chapter15... and https://github.com/norvig/paip-lisp/blob/main/docs/chapter8.... which are a few hundred lines of Lisp each, but do enough to be interesting.

A few newbie questions about lisp
You could look into Paradigms of AI Programming by Peter Norvig which might interest you regardless of Lisp content.

Mathematical paradigm?
Lisp has great power, examine PAIP, part II chapters 7 and 8.

Evidence that GPT-4 has a level of understanding
A computer running Prolog reasons, and that only requires a couple of pages of code. So it seems feasible that the network could have learned some ability to reason within its network.

Conversation with Larry Masinter about Standardizing Common Lisp
IMHO it's because lisp shines to manipulate symbols whereas the current AI trend is crunching matrices.
When AI was about building grammars, trees, developing expert systems builds rules etc. symbol manipulation was king. Look at PAIP for some examples: https://github.com/norvig/paip-lisp
This paradigm has changed.
