Re "is fast as can be": in my experience generating C/Zig code via Codex, agent generated code is usually several multiples slower than hand optimized code.

Yeah, I’m sure my Claude generated email client could be even faster if I wrote it by hand. Modern computers can retire billions of instructions per second per core. All operations that aren’t downloading or processing gigabytes of data should be instant on modern computers.

Claude’s toy email client gets closer to the speed limit than Gmail does. Why is Gmail so slow? I have no idea.

Given parent and GP are both using Claude... have you tried Claude? (I say this as someone who has not tried Claude recently. I did try Claude Code when it first came out, though.)

		First, it is important for these discussions that people include details like I did. We're all better off to not generalize. RE: Claude Code, no I haven't used it, but I did do the Anthropic interview problem, beating all of Anthropic's reported Claude scores even with custom harnesses etc. It's not a dunk that agents can't produce "as fast as can be" code; their code is usually still reasonably fast; it's just often 2-10x slower than can be.
