"The youtube polyglots have you fooled. They string together a few lines of some bland preselected topic in multiple languages. "
I agree
“I laugh out loud when they get to Russian. I have only seen three Westerners who can speak Russian fluently (all still have accents) who did not grow up with the language.”
then you have to improve your social activities… I guess there are more than 3
“They stun the Russian speaking world. It is that rare to find. All of them have been students of Russian for decades and have spent years in the former Soviet Union. To become fluent in such a language requires many years of dedication and a complete lifestyle change.”
just a couple of years… wait, a lifestyle change? err… I do not like this kind of religious approach, sowy
“You can’t just finish an Assimil book and claim fluency.”
I agree
“If you think that Arguelles speaks 10 languages fluently you are gullible.”
for me, fluent isn’t the same as near-native and I don’t think we need more than 5 years to be darn good in a language if we really work our socks off… so, in short, yeah I am gullible by your definition and not so much by my 5 year one
“I doubt if he speaks five languages fluently. He might read 5 languages very well, but that isn’t the same as speaking and understanding the spoken word.”
in fact, it’s not that hard… I don’t know if he speaks or doesn’t those langs fluently, but it seems to be he’s got a pretty good lvl in most of them
“Fluency is a very high hurdle to get over. You actually don’t need to be fluent in a language to conduct day-to-day activities. Nor do you need to be fluent to hold basic conversations.”
yep
“John Beyrle is the name to youtube if you want to see an authentic American speaking amazing Russian. He was the American Ambassador in Moscow. He was like a circus freak to Russians. They couldn’t get over his command of the language (still accented though). Actually, it was simple. The man is brilliant and spent decades studying and living in the former Soviet Union. Decades, not years. Think about that. Thousands of Western men live in Russia and Ukraine. They almost all have young wives and kids. Some have lived in the region for more than 15 years. I have never met one who can speak Russian fluently. Never. Some speak it well, but not fluently.”
maybe your standards are a lil bit too high (or even delusional)… I know there are some people who just don’t care about getting a good level but that’s a different story… if you work your ass off (plus good materials, exposure and motivation) you wouldn’t need more than 5 years to get a C2… but yeah, most people are lazy, and I AM “most people” 
“Yet, there are youtube characters who claim they learned Russian by finishing a “Teach Yourself” book.”
for me that’s not that bad… they’re not saying they’re gonna get a C1 level in 3 months at least (opss xD)
“My language goals have nothing to do with fluency. Nothing to do with impressing anyone. My goal is to discover and share. That is all. I would say that 98% of language learners are the same. They want to watch tv shows in a foreign language, read magazines in a foreign language, travel, and meet new people. They are curious about the world outside of their own. For those folks every step has its own joys.”
you’re damn right… I approve this message… nope, only this paragraph…
