"We get stressed out and are unable to problem-solve"
Studies also show that browsing the internet every so often at work relieves stress and actually helps people work better. Also, people can have multiple programs open/do multiple things at the same time at work without the Internet.
"creative ability dimishes"
Searching the internet might actually stimulate your creative ability. Easily seeing what other people thought of or have done may help you with your own ideas or help improve an already existing one. Cuz well... you probably don't have a unique idea anyway. Maybe the Internet is not dimishing creativity. Maybe it's showing us that we aren't as creative/unique as we think we are.
"Google is replacing our brains"
Okay. This is real dumb.
First, if you're constantly googling the same thing, it'll stick in your head whether you like it or not.
Second, you can still remember things you've read only once. It just depends on the type of person and how well he or she remembers things. Googling it versus reading a reference book or something doesn't really make a difference.
Third, with how easy it is to google things, you are probably learning things you wouldn't have cared to look up before.
I would argue that Google (wikipedia too) is actually helping us learn more than we ever cared to learn.
"If google were to explode, so would our memories"
Only the stuff we didn't deem important to remember. I'd still know how to do my work and get through everyday life. It would take a bit longer to find answers to questions you don't normally ask, but that's about it.
"Facebook: avg 245, we know 73.2%, only hang out with 4%"
There are different levels of friends. You can't just assume that everyone I'm friends with on Facebook is my bestest friend in the world. Some you're just acquaintances with and you want to keep in contact somewhat. This is better than jsut exchanging emails or phone numbers because this opens up interaction via posts and comments from one of the people that wasn't necessarily directed towards the other, like posting a neat article. He likes the article or comments and BAM there's more interaction than there ever would have been without Facebook. Maybe this helps them develop their friendship.
What about penpals? So I have to pysically hang out with someone to be friends with them? What about all my college friends that live in completely different places but still want to talk to?
I'm pretty sure this also doesn't take into account fake profiles and such.
"Heavy internet users are 2.5 more likely to be depressesed"
Maybe it's because we have access to everything that's going on outside of where we live and what the news cares to share with us. Maybe all the stuff going on outside our bubble depresses us because we get to see humanity more often. Maybe it's because all the non-internet users are just blissfully ignorant of technology and the way the world is going.
