Sure, again it really only matters if the search engine can filter the stuff we don't want to see, and show the stuff we want to see. If they can do that, we don't have a problem. It's the same as it was.

If they can't do it, we have a problem.

I guess there's the additional problem of bots posting comments everywhere, but that's really just a problem for social media sites and so I'm fairly unsympathetic.

People do spend a lot of their time these days on social media, but that's a new phenomenon, and I doubt it will last, so I don't think the future web is ruined.
