~3 months start to finish and the price of 1 engineer for a year, to rewrite a critical infra codebase that tens of millions of user software relies on. Truly the goalposts keep moving. This kind of project would've have been 10x the effort and price a few years ago.

Yeah, crucially, a lot of such projects never get greenlit.

Claude building stuff means a lot of things that everybody wanted to do, just couldn't allocate the attention or other resources - now get built.

It's likely much closer to that price if you don't calculate with subsidized token pricing.

Once a model like Fable/Mythos is trained, that was used for this project, the inference costs are profitable. CapEx vs. OpEx. Every new Zig->Rust port of this caliber using Fable/Mythos costs the standard token price, it's not subsidized. The model already exists for the original CapEx, you can do 1,000 ports of this for standard token pricing.
