I notice you pointedly neglect to even touch on my anecdotal experience that says that it's a trainable skill.
And yes, he's 100% implying that this boy practiced to get there. He's not saying that he's going to be able to train any random person to get there with an online course, but he's 100% saying that this boy practiced the skill.
Your "anecdotal experience" is just your words. It can be (and most likely is) just a lie from some internet rando. Did your wife (or who trained who, I don't remember) document the progress or followed some methodology that's proven successful and reproducible? How do she know her kids didn't have it before "training"?
Beato's explanation is that his son was exposed to a lot of different music since the age 0 and at some age they noticed that he associates sounds like "hey, microwave sounds like star wars". Nobody drilled sine waves 5 hours a day. His whole point is that you need to immerse children into the world of tones, that will train to "see" them.
I'm not "embracing" it, it's just what Beato said. He could lie, just like you did. The result is clearly not guaranteed, it can be coincidence, it can be a lucky gene in DNA or something else. I didn't see a paper that would study two control groups of children, one exposed to classic music, one not. All we know is children in families that speak tonal languages have it more.
> No one said anything about drilling sine waves besides you
Hey, maybe you forgot, somebody trained their kids not long ago, doing this lol.
Nevertheless, my initial point was that for now it's close to magic. Some, 1 in 10000, people are blessed to have this additional sense (at least for the first 40-ish years of their life), and others are not. It's a subjective perception of the thing indeed. If that doesn't awe you – well, ok, it doesn't hurt anybody. After all, every beautiful sunset is just you rotated away from a ball of plasma.
