I have a lot more I could say about this, but of course I'm not advocating some "don't watch anime at all" viewpoint.
I'd like to think that over the course of twenty-something-odd years, I've tried to provide a nuanced and intelligent viewpoint here.
I just don't agree with promoting known scammers as authorities on the Japanese language.
If you don't really know who these people are, what they're promoting, etc., it is very disingenuous to tell a beginner "you should listen to MattVsJapan and KenCannon".
That's literally all I'll say about this for now.
I don't think we really disagree on this, and neither of us are advocating for either extreme of "anime is THE path to fluency," or "stay away from it completely," just that it
can be a helpful study aid if it keeps you engaged, and you have the ability to discern what's useful and what's unrealistic--therein lies the crux; aside from just exposure and giving the viewer an "ear" for Japanese, they must have a foundational grasp of the language to really benefit from Japanese content as a study aid.
I haven't looked so much into all these youtubers and their various courses, so I wouldn't endorse any of them without knowing more; I should have made this more clear. I've only watched a handful of videos of Matt, or interviews with him, and I always duck out at the end of these videos when they start promoting their own stuff, so I didn't even know he was peddling his own course. This is literally the first I'd heard of Ken Cannon, so all I had to go on was the content of this one conversation, which seemed relevant to the question asked in this thread. I didn't mean to upset anybody by linking to his video, and after listening to the whole interview I realize that they indeed do play up their "input" methods and downplay the fact that they both
also pursued traditional study methods (and had that foundation I mentioned above). I won't rewrite my original post but I did add a note to encourage reading on.
It's clear that part of the branding of these new youngsters is based in the same populist marketing techniques that claim to offer a quick shortcut to fluency, or address a blind spot in "traditional" learning methods (quite a few of them have zeroed in on pitch accent as the long-ignored lynchpin to sounding fluent). I agree, it's misleading and unethical, but it's also part of the "hustle" these days, where social media has pushed people to making more extreme claims in order to stand out amongst a crowded marketplace... just look at the ridiculous video titles people use on these channels to attract clicks and play to the algorithm, even the title of interview I linked is bombastic. Some people embrace these tactics and enrich themselves, while others hold to their morals, even if it means their voices fade into the noise.
I also agree that that's exhausting and discouraging if you haven't become numb to the cacophony, but I encourage you to not give up, and if you want to warn people against people you think are operating in bad faith then I appreciate you doing so.
Personally, I've considered making my own materials focusing on the phonology of Japanese, which is more about the way the mouth forms the sounds of a language and the rules that affect them, as I find this covers not only the pitch accent errors made by language learners, but other more fundamental mistakes that make foreign speakers stand out. But aside from a little bit of schooling and a fading modicum of fluency, I'm just some guy with imposter syndrome, who would listen to
me? But then I look around and see all the people just BSing their way into success, and I realize that I'm far too hard on myself. Nobody knows
everything, we're all just trying to make our own contributions in the hope of being of benefit to others.
