I think you're getting close to ad hominem. It should be sufficient to point out how little overall people like Blow have accomplished. Blow is a hard worker, and yet it took him and his team 8 years to develop The Witness, which as you pointed out isn't anything revolutionary. I think there's a weird form of elitism at play here. Working close to the hardware isn't hard. There was a point in my early 20s where I too felt like I'm better, because I know how a computer works, or that making games in pure C is harder than in C++. As an adult this is cringe. I work in embedded, and I can tell you there's enough low level programmers out there to threaten my job security.
