But what separates them, and what they think people will eventually realize is that living in the moment is healthier, more rewarding and authentic than doing things for the purpose of likes and attention. Instagram is touching on this with stories that they copied but the entire Instagram platform just feels grimy overall (and snap is starting to feel that way as well with their uncustomizable discovery page).
So the path I see is them really focusing on authentic communication, and making the best ways to let friends share their true selves without worrying about likes because that's when you can have more fun. I think instead of being a camera company snap should be the 'moment' company. To me, there are lots of ways to enable people to have engaging experiences with others in the moment outside of a camera.
This video by Evan sums up the difference well too: https://www.youtube.com/watch?v=SQYBLeV6sbM&t=7s and also see Kanyes tweets (https://twitter.com/kanyewest/status/1042779425048211456?ref...) on the matter :p
