Of course, the definition has shifted since we were young:
In my day, the word “Awesome" was reserved for things like curing Polio and walking on the Moon, not for food or TV shows.

“In my day” generally indicates a Get Off My Lawn sort of person, and Dr Tyson is fairly close to my age, so I really wouldn’t hold it against him. Someone younger, though, might take umbrage:
Okay. I feel about NdGT’s linguistic arbitration about like how I feel about Richard Dawkins holding forth on anything BUT Evolutionary Biology: “Who died and made you King?”
I mean, just because the guy is famous and has some clout (possibly unmerited, I don’t know. I may be biased because I am suspicious of people who have an advanced degree — like Dawkins — but get famous mainly for their pronouncements, or their outrageousness (that’s Dawkins again), or for being generally smooth and good looking (Not Dawkins).
But yeah. Why should I consider his opinion on how I should speak any more heavily than that of any other non-specialist in elocution or whatever.
A person may be an expert on topics A through Y and yet not know squat about topic Z. I know my mouth occasionally writes checks no brain I know can cash, but I try to avoid sounding like an expert.
And there are always occasions to ask “Who died and made you King of anything?”
