Imagine living in a world where firearm ownership is as common as owning a smartphone; what are your immediate thoughts or concerns?

I would be terrified, because not everyone should have access or be able to carry a gun around and the more common it is the more issues it will cause.

That I would need to carry one with me where ever I go since its most likely not safe

If people were all responsible with them they would be no issues but that would never be the case and having too many irresponsible with guns will cause more problems than solutions
