An enormous and sophisticated 'tool chain'. Surely it could never be implemented in a one-day-to-be-invented universal fabricator? One is reminded of those 19th C ppl who thought recorded music was impossible since any player would have to contain miniature versions of all the orchestral instruments (or things that resembled them: "humanity's choir") together with a horrendously large paper roll punched full of holes

If you have a large enough supply of electrons, protons and neutrons, and you can combine them at will, you can make anything.

[lifeformed]

Anything except for quarks.

[jacquesm]

If you bang some of the electrons hard enough into some of the neutrons or protons you'll even get quarks.

[ars]

No you won't.

You need to bang protons or neutron together. Electrons don't participate in color force and can't make quarks.

[jacquesm]

Hehe, trust me for getting it wrong, you are absolutely right.
