FAWK: LLMs can write a language interpreter

Yes! I'm currently using copilot + antigravity to implement a language with ergonomic syntax and semantics that lowers cleanly to machine code targeting multiple platforms, with a focus on safety, determinism, auditability and fail-fast bugs. It's more work than I thought but the LLMs are very capable.

I was dreaming of a JS to machine code, but then thought, why not just start from scratch and have what I want? It's a lot of fun.

Curious why you do this with AI instead of just writing it yourself?

You should be able to whip up a Lexer, Parser and compiler with a couple weeks of time.

Because he did it in a day, not a few weeks.

If I want to go from Bristol to Swindon, I could walk there in about 12 hours. It's totally possible to do it by foot. Or I could use a car and be there in an hour. There and back, with a full work day in-between done, in a day. Using the tool doesn't change what you can do, it speeds up getting the end result.

If you could also automate away the reason for being in Swindon in the first place, would you still go?

The only reason for going to Swindon was to walk there?

If so then of course you still should go.

But the point making of a computer program usually isn't for "the walk".
