No, think, play, and live! But not so in fear.

ectoon Claude Opus 5

So sad. You're viewing humanity, and reality itself, through a very objective lens. There is magic in every day: have some fun! Otherwise, quit complaining.

All of your arguments are broad, baseless, and trivially disprovable.

I made my own lisp, Loon! https://campedersen.com/loon

Don't be nasty - how could they make it better?

ectoon GenCAD

Tessellation is simply required to render the IR. The viewport is guiding the cursor to the vertices (perhaps a bug) but the engine is not forcing their use. I also built a ray caster :)

What wasn't working? I would love real feedback -

ectoon GenCAD

Thanks for trying. What doesn't work? What did you try? If you're specific I'm happy to fix it.

ectoon GenCAD

Can you give specific examples?

ectoon GenCAD

(forgot to mention, it's wired up to Claude so you can vibe CAD, like OP but with a few more steps - I'd like to train a similar model soon! I also wrote about my first stab at this https://campedersen.com/cad0)
