I'm optimistic about the future. I'm jealous of kids growing up today. Little kids have tablet computers that are orders of magnitude faster than my first PC I got in middle school.
Kids growing up today will invent new technologies we haven't even thought of yet. Who would have thought 20 years ago that we'd all be carrying around tiny computers that will change our lives for the better? A little screen you hold in your hand can give you access to the total sum of human knowledge, and anyone can afford it. You can press a few buttons on a screen to hear pretty much any song ever recorded. Read pretty much any book ever written, learn more about any subject than you could ever learn at a library 20 years ago. Communicate with people anywhere in the world whenever you want, all from a little thing you hold in your hand. Kids who grow up with this kind of technology will take it to places we haven't imagined yet.
I wrote a paper analysing this subject. My conclusion is that we as a whole are screwed. We have all this great technology allowing us to communicate ideas instantly anywhere. Instead of doing great things to improve our world with this. We choose to use our technology for entertainment purposes, or warfare.
Todays youth would rather have something done for them, than learn how to do it themselves. I find this especially disturbing given the amount of information that is available on damn near any subject you can think of. I really hope my experience with 'the younger generation' are an exception and not the rule. But it sure seems there is a whole-lotta stupid running around these days.
Grumpy old man rant complete.
