You don’t have a biological problem, you have a sociological problem. Specifically, a logistics problem. And logistics is a function of infrastructure.
So any issues an able-bodied, sound-minded adult is going to have with learning (getting used to) a language will be entirely due to infrastructure, not linguistics, not biology.
Well, because even minor inconveniences add up.
For example, a minor SRS annoyance is going to cause major issues, because virtually everything you do on your SRS, you do hundreds, thousands, tens of thousands of times. Reps alone are going to be a 5~6-figure proposition. Each rep takes multiple clicks…you can see how things add up.
Similarly, being unable (or under-able) to operate a PC is going to put someone at a disadvantage in that they’ll be unable to leverage information technology to overcome borders and create habitual exposure to the language oh my gosh that was a belabored sentence
Next time you want to blame your biology, your schedule or even your character…
You find time to text people you don’t even like, to show off your socioeconomic status to old schoolmates on Facebook, to check your email every 3 seconds instead of doing that one important thing that would actually change your life for the better.
It could just be that it takes too many clicks to get to something Japanese.
How many clicks away is the nearest Japanese website? Book? Movie?
You’re far less likely to change the channel if the remote is far away.
Even once you have the remote, you’re likely to cluster around a bunch of nearby (adjacent) channels — you’re far more likely to go up and down than to jump out 100 channels; not because you like the nearby channels better, but because they’re the easiest to get to. Because they’re closeby. Because they’re there.
If the metaphorical Japanese remote is too far away and too complex to use, you’re not gonna use it.
