The only solution to your problem then is to hop into a time machine and somehow change western ideology.
As population increases, social anxiety increases - that's just the way it is. I'm not sure that Nintendo or Niantic ever claimed that this would solve obesity or abnormal psyche in the American population, but believe it or not I've already had multiple encounters with polite strangers because of this game. And is the content of conversation so important that to not talk about the "right" thing is worse than to not talk at all?
I disagree entirely with what you're saying, because you sound like somebody who has never had problems striking up conversation with a stranger - which is obviously preferred. But for those people that have esteem issues - this is a big deal. I'm not saying I am one of those people (quite the contrary), but this game is giving young people in a busy world a common ground of entertainment. It deepens the social sphere and unifies the population - transcending gender, age, or ethnicity. Is that not a beautiful thing in today's society? With police brutality and racism running rampant?
Quite frankly, I find it belittling that you offer such a simple solution to such a common but difficult issue. Not trying to start a flame war, nor am I saying that PokemonGo's objective was to solve any of these issues. However, this game is a unifying force in a nation and time of freaking ridiculous turmoil and bigotry. For you to say "just go ask somebody to walk with you" underlies your lack of understanding of social anxiety, and it would piss off those with social anxiety.
You're saying that the world needs more social interaction - this game provides that. It also provides a common ground between two people that may have previously had nothing in common save the fact that they are composed of carbon.
You're saying that it's sad that people need a game to relate on a personal level - so what is an acceptable subject to relate on? Politics?
We're also on a forum that centers around people talking about other people playing a game. So I'm just confused on this perspective.
Again, not flaming. It just drives me crazy when people are like "just go do this." It's like telling a depressed person to "just stop being sad."
