Interesting post. Very important issue. I like your optimism regarding AI. Let'shope it will be as you picture.
I do not get anxious about the actual outcome. I think I'll be gone by then. I get anxious about the period in between, the one I am living through. Less privacy, safety and social interaction (despite all the buzz about social networks).
I see it especially in children and teenagers. Their inability to interact with the real world, to use language adequately, to solve problems that involve socializing. They have grown increasingly alienated.
The environment issue is alarming and I am not very optimistic about that. I feel sorry about my children and grandchildren because there is not guarantee that they will have a healthy environment to live in. Most likely they'll be so busy in their gadgets they'll not notice until it's too late.
