My undergraduate degree was in electronic engineering, and I've always loved sound, hi-fi and guitars.
The first point your son made, I fully agree.
The second point your son made, I don't disagree. It's subjective, we are human beings and have different neurocortical 'specializations'/trends (call it what you want). I think my hearing is really good, I've always relied on that as my major sense at night, etc. My wife, her hearing is not so good. Her eye sight is probably not as good as mine either (I'm probably a tad over average in that department). Her sense of smell blows me away, it's so much better than mine. Tactile-wise, we are different again, but it's harder to define. Humans are complex. I try to study, research and understand stuff related to human beings in their environment and their cognitive biases (or some such word) - it's bloody difficult, I have some opinions which I can't well back up, but I don't know...
Interesting observations!
To me, the whole tone wood debate is a fun bit of academic forum sports. I get a kick out of it.
But, at a real-world, practical level, the type of wood doesn’t really enter my mind when I consider a guitar to buy. The style, aesthetics, workmanship, feel, ergonomics, and general sense of quality play a much larger role in my decision making. The only time I seriously consider wood type is for aesthetic reasons.
In fact, I don’t think I’ve ever chosen or wanted a guitar based on any anticipated tone wood considerations.
But, I’ll gladly bat the topic around on a guitar forum!
