His point is going to be some copium like since the c compiler is not as optimized as gcc, it was not impressive.

You probably don’t know what you’re talking about.

Why wasn't the C compiler it made impressive to you?

I found this was the least impressive bit about it https://github.com/anthropics/claudes-c-compiler/issues/1

It didn’t work without gcc and it was significantly worse than gcc with gcc optimizations disabled.
