The meme came true. People CLAIM they'd rather have a doctor on board their plane than a YouTuber but when the doctor IS a YouTuber their otherwise unimpressive abilities get buffed.
Besides, what if a passenger had an urgent vlogging problem, or had a panic attack due to not being able to compare smartphone cameras, maybe crippling drama-withdrawal symptoms, or simply needed to watch things move very very slowly? What use is a doctor then?! None I tell you, none! YouTubers will inherit the Earth!
After everyone useful has left.
