The odds of Roddenberry still being alive today are slim. He'd be 90, and unless he was in perfect health for a man that age, he probably would have passed away by now anyway.
I don't know about that, my best friends' grandpa just turned 99. Sure, he's in a retirement home, but that's irrelevant.
As to what Gene would think, no idea. Probably not much given that when he was alive,
he was busying rewriting everybody's scripts on the first two shows to suit himself, IF those stories are true. I wasn't there, so I don't know.
