I think the author is simply showing that Circle can implement Carbon syntax using its metaprogramming capabilities on top of C++. It is not making a statement that the syntax itself is desirable.

That's right. I'm fine with normal C++ syntax. But other people have other opinions. And there is an allure of getting to a CFG so that non-compiler tooling could build a parse tree and do useful transformations. That's a good a goal.

I'm basically looking to evolve on multiple fronts at once. If there's an interest in new syntax, put resources. If there's interest in a borrow checker (I'm sure there is), put resources there. Just move up the field however you can.
