Okay. Here is a very pretty idea that could serve as a foundational concept to mm-ADT.

There are only 2 types of mappings in mm-ADT:

<= obj    "objects      -- sets     "
<- inst   "morphisms    -- functions "

Hello Friends,

This elf begging to climb onto the web for Christmas began as a personal email, a review of Paul Graham's little Lisp Bel. He sprouted arms, legs, and in gingerstyle ran away. Arms for symbols, legs for conses: these primitives are the mark a Lisp — even more so than the parenthesis. What do we get when we remove these foundation stones: naming and pairing?

No pairs. No cons. No structure. Unordered. Chaos. Eve, a beautifully incomplete aspect oriented triple store. No need for legs when you can effortlessly transport to your destination. Lazy. Pure. Here and now, a retrospective.

No symbols. No names. No variables. Combinators. Forth. No need for arms when you can effortlessly push and pop your stack. No words. A world without words. Virtual worlds. Virtual reality. Space. Time. Motion. Action. Kinetic Programming, a proposal.

I apologize in advance. Checking my pocketwatch, I see I haven't t

I was drawn to programming, science, technology and science fiction
ever since I was a little kid. I can't say it's because I wanted to
make the world a better place. Not really. I was simply drawn to it
because I was drawn to it. Writing programs was fun. Figuring out how
nature works was fascinating. Science fiction felt like a grand
adventure.

Then I started a software company and poured every ounce of energy
into it. It failed. That hurt, but that part is ok. I made a lot of
mistakes and learned from them. This experience made me much, much
