I've been wondering about this lately too... how the "real time web", as it's been termed, will play out, and how will people interact with it.
As the flood of available information grows, so too grows all the different ways to filter and access it.
The limiting reactant may be the processing speed/power of the human mind, even as filtering/accessing options and content compaction increase.
But before we all have artificial neurons, I think it'll be a wild ride of problem solving and new problem creating.... with many getting financially engorged, increasing empowerment of the "little guy", and hopefully greater compassion felt across the spectrum of humanity.
There's little doubt in my mind that mobile access (via browser or app) will continue to become more important. And there are far more mobile phone connections than computer internet connections worldwide.
