My biggest fear right now is one day people will just stop thinking. We'll reach a point where we automate our critical thinking, creativity, memories, etc. to machines. I get worried when I realize I put a reminder on my phone for certain tasks like: "Go to the post office on Monday" when that should just be something on my mind already. I also think about how sites like YouTube and social media are not just time sinks, but also force you to think about subjects you otherwise probably would not have thought about otherwise (good or bad, but mostly bad). Anyone else thought about this?
