Well, it doesn't do everything. Actually there's a lot that it
   doesn't do but there's a lot that it can do. Ok That sounds
   obscure. Let's see... if I wanted to write a new game, I
   wouldn't use LISP. Java. Python. They're great for that. Better
   still, a game development environment like Unity 3D or go
   hardcore with C++. These languages are all-purpose, if I had a
   goal in mind, it's heavy with graphics, sound, connectivity
   (networking) and they're perfect for making games.
   HTML+Javascript are still kinda your only choices for doing
   stuff that works on web browsers, whether games or anything
   else, and you have to add on a lot of things to make it work,
   but there's awesome stuff for that too. But so why am I excited
   about LISP? I want to talk to the computer. I want my computer
   to understand me. I want to understand my computer. The reason
   why LISP is used so much in real-world AI (great examples are
   solving the very complicated "get your cheapest airfare" problem
   when the airlines are top-secret about how they do things. Or
   the only commercial quantum computer - that was written with
   LISP)... is because it's raw power that can do impossible
   things. I don't know what I'm going to use it for or even if
   I'll succeed in really learning it (or Scheme, which is used in
   some games and is its close cousin): But see, here's the thing
   I'm getting out of it: With LISP, my computer is learning right
   along with me. It doesn't do much by itself. I don't even know
   what I'm going to do with it. But it has flow - I "feel
   connected" to what I'm doing. It tells me right away if I don't
   make any sense. It does what I tell it to do, yes, but it really
   forces me to think, WHAT AM i DOING? And really, I have no idea
   what I'm doing. But it's like planting a seed of an unknown
   plant. What will it grow into? Will I be able to give it water
   to help it grow? If I get it to grow, how will it branch out?
   How will the branches branch out? Will those branches reach down
   and connect with the root? Will one of them reach the sun and
   come back again? I don't know. That's the kind of feeling I'm
   getting, and I can barely add two numbers in reverse polish
   math. (it uses ( + 2 2) to tell me "4" rather than 2+2) I guess
   mostly it's because it uses lots and lots of parenthesis. Things
   inside of things inside of things inside of things inside of
   things. It creates structures of connected things. When I learn
   it, I'll be able to have it talk to itself and change its own
   code. So what does it do? I have no idea. It's like someone
   plopped an alien baby and said, "You. Care for this baby." and I
   have no idea what it eats - IF it eats, if it needs water, if
   water is acid to it.. how will I get it to understand me? How
   will I understand it? and it's confusing to most programmers,
   which makes it different and I'm contrary. It's older than me
   and helped build the very Internet we're on. So, really? I don't
   know what it does yet. It doesn't know what it does yet. The
   whole thing confuses me like crazy yet it seems so simple I feel
   like it shouldn't confuse me at all.. and that's what I love
   about it. I feel like I'm about to dig various tunnels in the
   dark. It's that "feeling" - that experience that I'm after, not
   something to show off to other people. Reading the things people
   write about LISP that love it, it has almost this religious
   quality to it and on page three of a tutorial (I spent more time
   reading ABOUT it than actually doing it yet) - I'm getting 'that
   feeling' of excitement and exploration. So, practical? Probably
   not. It's just a "deep thing" that I really want to understand.?
