When you say "most people still use PCs" like PCs was an obsolete thing makes me shiver. For me desktops are the center of our digital life and mobile crap are only an experiment to make anybody slave of few services that's somehow succeed but it's of course doomed to fails like "netbooks" in the past.
Unlike netbooks, which were underpowered laptops released ahead of their time, mobile devices have already hit their critical mass of users. Kids grow up with phones and tablets instead of computers, on average, which makes real computers a much scarier and less interesting proposition.
On education: personally I was taught a bit of unix at first even if my first computer came late (around 13/14 years old) and that's give me in very few time a set of skills I do not see even in many colleagues after years of professional work. Myself I learnt many thing in a very long time simply because I discover them casually and nobody help/taught me anything or nearly anything on them. Long story short: if we have proper school development of certain skills or at least a certain forma mentis/paradigma start to be easy and quick and pay off enormously during the entire rest of the life.
Of course I do not expect a phantasmagorical society formed entirely by PhDs and MDs but I certainly do expect a far different society with benefit for all of its components. The lack of competence and skill we observe these days, coupled with unemployment rates depict a clear scenario about that.
We have less and less competent people, we actually encourage people to be incompetent (like "hey coding at schools to forms legions of code monkeys able perhaps to write a hello world) saying the contrary, we obstacle due to the architecture of the schools, society, companies etc skilled people to express, cultivate and grow their potential and as a results we do not know how to evolve anymore.
We produce more and more crap, we have many companies more and more dependent on few, typically aging "consultants" the few that still know how to work etc.
That's can't last in the medium/long term and recovery is super-difficult and super-long.
Maybe the only thing we can be grateful about is that it takes less to be on top(+)?
+: Of course, I know I'm certainly not on top, especially looking at some of the really impressive Show HNs that I see quite often, but compared to the people who I work with and the people around me in real life it doesn't take as much as you would think to be the best among them.
I fear this future because while takes less to be on top we do not live to race, with live to live. We are not autonomous, we need society, other expertise and work and that's pose a super-big problem even egoistically for us. Not even counting for our society at a whole and for future generations...
I've found that using Hacker's Keyboard conforms my muscle memory and lets me use a touch keyboard faster than I would otherwise be able to. It seems not everybody benefits from this.
