With upfront apologies for applying neuroanatomical fairytales on left vs. right brain: Let's suppose there's a truth in it about different brain capabilities: The above is a model of hive mind capabilities: Browsers observe the web, aggregators feed the observations, suitably noise filtered, to a learning-and-compression facility. As is evident from the above, we are undersupplied with learning-and-compression* engines. I could have named the other search engines like I name the browsers, but they just do the same thing, whereas you and I don't do the same thing at all when we scan the web. What we need is an explosion in specialised search and some "smart" way of using all that search at once.

*Indexing is compression and compression is knowledge.
