I'm also pretty excited about the advances in technology which are making life better. The access to information via the internet is so meaningful that it would be hard for me to go back to a time without it. We have access to an almost unlimited library from our homes. This could make people more intelligent who use it as a tool. Education is being revolutionized by the new tools in ways far superior to the old classroom lecture format.
It is also possible that the social networking sites are a step towards achieving more social cohesion in our world village. It is true that the connections are not as deep as a good friend down the street, but for someone like me (and for people I know with Aspbergers and other socially limiting issues), it provides a way to connect. I mostly enjoy FB because I can click "like" on projects of fellow musicians, some very accomplished, and establish a positive reputation. I can also reconnect with people from all the places I've lived. I would never be able to think of a pretense to contact them outside of these networks.
I will have to confess that I actually don't know what people mean by "attention whoring", or why it is upsetting. When I see people post accomplishments, I especially enjoy reading about those. The only thing I personally dislike on FB is when those weird little soundbite memes (pictures involving jokes, political comments, kittens, or inspirational comments) are all that come up in the feed with some repeated many times. I think those are silly and I'd rather hear what people are doing in their lives - whether it is the laundry or recording an album. Either way it helps me to get to know people better.
