> Also what's up with the people hiking (by themselves) with a bluetooth speaker. You're by yourself, in nature. If you want to listen to music wear headphones!!

I used to hold this same opinion. Unfortunately, times have changed and now everyone is constantly in their phones, isolated in their own universes, typically with earbuds or headphones. At least the obnoxious speaker dude is present; in a shared physical reality with the world around him. A lesser evil.

This is why god invented bone conducting headphones
