I don't want to read the whole thing because it looks like it's very cynical - it judges TCS scientists who believe in Grover speedup as naive because they are unaware of real life noise, without actually realizing that's the point of TCS. We don't know how noise will scale IRL so the job of theoretical scientists is to design the basic units of quantum computation regardless of how it may or may not work IRL. It's like judging XOR and NAND in 1920s because transistors maybe won't be able to simulate them.
