The difference is between 50% online being disinformation and 99.999999% being disinformation as content is overrun with cheap bots. Think of what happened to Usenet except worse. Instead of forums being overrun with ads for V1agra, social sites with be overrun with fake members posting reasonable sounding stuff that is laced with coordinated tactical falsehoods.

I think eventually every piece of information will have to be digitally signed and our devices will by default limit what we're exposed to based upon whitelists.
