It’s awesome to do cool, fulfilling things and for some of those things you need a computer. For others you don’t.
I really don’t see why everyone should use a computer, given the wealth of possibilities out there.
Also, I’m pretty sure the death of the PC doesn’t mean any of what you are insinuating. It will be more like the death of horse riding after the advent of the car. (If I want to go horse riding there is a club that offers that not five minutes from where I’m living. Horse riding is dead – but that doesn’t mean it’s impossible or even hard to go horse riding today.) Only that PCs will probably be an order of magnitude more relevant than horses are today and, while not always as relevant as in the past in certain contexts (at home), they will still be relevant in others (some work, academia, …).
I’m still pretty confident in the prediction that the PC at home will die. (Which will not mean that no one will have one at home. Just far less people than today.) I’m also pretty sure that the PC at work and in academia will not die.
