Access to infinite knowledge from the internet, sitting right in everyones pocket. Sometimes, I will find myself talking to someone a few generations older than me. And they will say something along the lines of "I wonder how many..." and then just let the idea rest. Because they still act like they would have to go to a library to look up the fact. It amazes me! We don't have to wonder. I can look it up right now! It'll take me a few seconds.

Alternatively, I cannot stand when I am talking to someone and make a statement to which they respond: "I don't know..." or "I'm not sure if that's true". This is often a tactic I see older men use (often talking politics) to cast doubt on a younger or female person. And unfortunately, back in the day that was good enough to derail a conversation. Nowadays though... Don't believe me? Let's look it up. We don't have to take your word for it. People forget they can be fact checked in real time.
