Are you kidding me? Look at his wikipedia? http/en.wikipedia.org/wiki/John_D._CarmackPrecisely. I don't care that he was "a god of gaming" in the 90s, that was then - this is now. Tell me guys, what did Carmack work on recently that deserves my attention as a gamer?
All that said, besides the graphics, they seriously need to come up with better ideas for games. Military shooter crap got boring, BF3 or not, it's all the same boring BS. Haven't seen a worthy RTS since Dawn of War 1 (but that's just me, I guess, I have very high demands from an RTS). More or less innovative and entertaining series get overtaken and stomped into dust by EA. I'm literally at the point where I have money for a graphics card upgrade and don't care, because for what? Consoles or PC, originality is what really suffers nowadays.
Look at his recent achievements. He is a pioneer of gaming and will always be. The games you see on the shelves nowadays were made possible because of Carmack.
Would you say the same thing about Bill Gates? Oh whoopity do he created Microsoft but hasn't done anything I've noticed in the past few years so we can entirely discredit his opinion, right?
