This seems like such a jerk move to reply to someone who worked hard and is excited about something to essentially try to tell them it was worthless. Whether an LLM will ever actually be appropriate as a compiler or not, the reply from Chen Fang is in such poor taste.

Don't take it seriously, It is Twitter bait from an intern.

> I wonder whether its possible to trust an LLM to "compile" your code to an executable and trust that the compiled code is faithful to the input without writing a static validator that is pretty much a compiler itself.

"LLMs as compilers" do not make any sense.

Traditional compilers must be deterministic to compile to the correct machine code for the correct architecture otherwise the executable will break.
