The point I'm making is that I believe that people who have mac skills will need to also learn Windows skills just because it's so much more commonplace.

Just like lefties can be more empathetic on scale, because they have to face the disappointment of things not being designed for them (us, but I'm more mixed-handed than pure lefty).

It's not about the orientation of the hand, but the phenomena surrounding having to orient your hand / use a certain hand in a certain way.

Just like I don't believe that Mac as an OS is inherently changing the kids significantly.

Please do apply adequate scientific rigor here!

And to be fair, I don't really know anyone who's only ever used a mac for those exact reasons. We had a few kids in graphic design school be like "well I mostly use Mac as my personal computer is a mac", so they weren't as used to using Windows, since they hadn't done it since school.

Like if you compared the linguistic capacity of people in the US, I'm pretty sure that no matter what you choose as the primary language, those kids will still know English (as we're talking about USA here), and if they know English, then they're at least bilingual, which has a lot of cognitive benefits. But you wouldn't be saying that specifically speaking some specific other language makes the kids smarter.

Some languages might give certain advantages, like say some aboriginal language which doesn't have left/right but always uses cardinal directions. Due to them doing that it's insanely hard to confuse their inner sense of direction, even if you chuck them if a van and drive them around blindfolded.

So I'm not saying using Macs can't have some such small specific advantage, but I doubt it, and think it's just general adaptation skills, which do correlate with positive cognitive development.
