The most dangerous part of this addiction is that it doesn't
feel like addiction. Suppose we spend 4 hours in an afternoon consuming random content - starting somewhere on a Google search, landing on Wikipedia, end up reading dozens of articles on various topics in that 4 hours. Unlike alcohol or drugs, this is
knowledge addiction - afterall, we learned about a bunch of things in those 4 hours, didn't we? We didn't spend any money (well, other than the laptop, electricity and internet bills), we didn't harass anyone (like alcoholics sometimes do) etc. Heck, we didn't even "waste" time like we
think we do, when we play video games. So it feels somewhat better.
But, all that we learned in those 4 hours - is it really that useful? Some of it might be, lets say an hour of it. What about the other three? That could have been spent on something healthier - having fun with friends, play sports, or even just sleeping!
I understand the irony of typing this, but I too am in the same boat - consuming things voraciously, most of which is just useless knowledge, at the cost of relationships, health etc.
