How is the syntax new?
It looks like lispy - see the outer parens in the examples given.

Heh, every time you show a average developer lisp for the first time the reaction is the same. Little do they know conditionals, GC, REPLs, macros and more comes from the syntax and language dreamed up in the 50s/60s.
I don't see why Lisp's history would necessarily imply the family is worth learning in 2026. What (other than macros) do lisps offer that other modern languages don't?
Just saying "macros" is a bit reductive: in CL, you have access to the full language at (read) parse time, compile time and runtime. Said macros also mean that logical OR/AND short-circuiting isn't a compiler black box, you can implement such behaviour easily yourself.
------
The syntax is actually a big pro for a lot of people. I love its streamlined look that basically reads like Python once you let your IDE indent properly and learn to see "through" the parentheses (CL, Scheme).
The original language where everything is an expression and it shows. Where Python still needs an ugly ternary and made match a statement, Lisp has had the perfect IF and COND since the dawn of time.
Symbols are still a cool and useful concept that almost no other language I know of got.
The numerical tower - despite being full of holes in CL - is amazing. Built-in rationals and "correct math" as sane default (i.e. 1/2 not returning 0) never get old.
------
And if you let me rave about CL specifically (e.g. DECLARATIONs as "#pragma done well", restarts, CLOS/MOP, runtime READ/COMPILE, etc...), there are a lot of cool features barely copied anywhere that'd improve other languages, but these aren't part of "what make Lisp Lisp".
You don’t program in Lisp, do you? I used to be confused by the smug Lisp weenies. Now I am one. And the difficult thing I’ve found over the years is that Lisp is sort of unexplainable. You either “get it” or you don’t. Yes, it has macros, but macros are a bit overrated. I’ve been programming in Lisp for decades and I rarely write macros. I think the thing that is difficult to convey is how powerful Lisp’s core execution environment is while at the same time being just a page of code that a CS undergraduate can understand. Literally everything else is a library. And those libraries can create syntax, generate code on the fly, and do many other powerful things. But most people won’t “get it” until they take the plunge. I didn’t. Until I did. And now, I don’t feel a need to defend Lisp at all. It won’t go away. You can’t kill it. The folks that “get it” will always have it, and those that don’t “get it” will reach for their Blub language again and again. Such is the way of the world.
