In addition to what you wrote above we are entering phase where written content will not be trusted (or perceived as produced by real human being) and there will be absolute, massive flood of it. Tightly walled gardens with ability to verify that participants are humans may strongly benefit from this development. I'm wondering if Apple is going to use this angle for their advantage if they have any concept for tech which could help to differentiate human generated content from bots.
