I think that's overstating it.

JustHTML is a success in large part because it's a problem that can be solved with 4 digit LOC. The whole codebase can sit in an LLM's context at once. Do LLMs scale beyond that?

I would classify both FastRender and Opus C compiler as interesting failures. They are interesting because they got a non-negligible fraction of the way to feature complete. They are failures because they ended with no clear path for moving the needle forward to 80% feature complete, let alone 100%.

From the original article:

> The resulting compiler has nearly reached the limits of Opus’s abilities. I tried (hard!) to fix several of the above limitations but wasn’t fully successful. New features and bugfixes frequently broke existing functionality.

From the experiments we've seen so far it seems that a large enough agentic code base will inevitably collapse under its own weight.
