I feel like an open source RV CPU is very likely in the high-performance space.

The amount of effort required to design and implement such a device makes it difficult for a single company to invest in, but many interested users of it could band together to create a viable open source implementation.

I guess it's a question of a project that such an effort can crystalize around.

Isn't translating between languages something that LLMs should excel at? I mean I'm sure it's more than just pasting it into ChatGPT but if the design has been validated and it's understood, validating the translated version should be several orders of magnitude easier than starting from scratch.
