This should never happen until the web radically changes. I'm fine with the "web" being the future if it can provide truly native experiences. It simply can't do that now.

1. People aren't downloading apps because they have most of the core apps they want/need currently, not because they're browsing the web instead. Look around on any college or high school campus. Barely anyone has mobile safari open. They have instagram, snapchat, a messaging app, and maybe Facebook open.

2. Bots are the future? We'll see. Nobody besides tech people seem to care about bots. I'm in tech and I don't even care about bots - yet. And again, look at today's high schoolers and college students - they don't care about bots.
