I think Fil-C is awesome and I very much like the style in which you present your work as well. (Hope I'm not being too emotional here!)

FWIW, I can see where TFA is coming from and I had the urge to write something "in defense of Rust" after listening to / reading some of your recent comments. I think your sister comment about the limits to Rust memory safety being real as much as the limits to Fil-C's performance and practicality is spot on, but the feeling (those emotions again) one gets from much of your commentary is that you downplay the latter quite a bit.

I think the real argument for Fil-C is that you aren't going to "rewrite in Rust" but you can often realistically recompile in Fil-C and pay the performance penalty; the fact that that Rust rewrite could also end up less safe is I think should be argued mainly from the AI angle where the only practical way is an LLM based rewrite but that would have a load of unsafe - way more than a "proper" rewrite - to be practical and the recent $100K Bun rewrite is a testament to that.

(I would love nothing more than for Fil-C to become as widely used as it practically can, since no other approach does nearly as much to secure C / C++ code and a lot of said code is out there; and security aside, it could prevent a lot of data corruption that most major C++ programs gift to their users.)
