Am I the only one who never got poliglots on YouTube?

I never got the talent of people like this. I think the only one that actually has some sort of talent for languages is this Channel. Many other channels I've seen, poliglotters, seem to lack some kind of a common sense, they can't actually communicate on anything more but the most basic matters. I understand that this must be a frustration for the people that actually spent their entire lives mastering languages as a profession.
