Literally the only reason it doesn't happen is because there's too much money to be made for people who are not you and me.

Frankly if it did happen, someone would bridge it and I'm sure that rogue bridge ain't gonna be poisoning anything. They'd be a hero and a broker.

This is a pretty gross oversimplification and it's also a mischaracterization to say it's "a more widely used and active version". I wouldn't even put it in the same catagory as traditional lisps since those will compile down to executables and clojure run in the JVM

You typed that like they're wrong

Thanks for saying something anyways. I wish more people would follow your example.

Your opinions are so regressive you really should consider going into management.

You're also manifestly wrong on "the free particle is the only system we can exactly solve".

Also, for context, my question was posed because the idea of "particle number" as well as "quantum states of particles (which are countable) represented in a Fock space" and in general the idea of particles are, like, page 2 of any QFT textbook. It doesn't approximate anything in the theory. Creation and annihilation of particles (and hence the well-defined concept of a particle) is fundamental to the construction of the theory itself, perturbative or not.
