Psychological Science can assuage your concerns: People are often concerned about whether technology is making irrevocable changes to our brains. Many folks fear that over-reliance on technology for school or work will cause lasting damage to theirs or their children's attentional abilities. Other folks fear that too much time spent on "smart phones" will hinder their ability to reason, read complicated text, or have real conversations. The truth is that these fears are unfounded. Every little thing you do is registered in your brain, but the only kinds of experiences that will have lasting negative effects are traumatic brain injuries. So do all you can to protect that beautiful head of yours, and feel free to use technology for what it was designed for: to supplement and support human thinking.
