where do ideas come from

I am finalizing a paper for an anthology Lisbeth is co-editing, and stuck with an excellent question Lisbeth (I think) wrote in the margin of the manuscript.

In the chapter, I write:

I will suggest five seemingly stable trends that, collectively or individually, have been the base of many predictions about future media for half a century.

(1) Convergence: the view that traditional media are melting together into new computerised media;

(2) Interactivity: everything will be deeply interactive, lending the power of influence and choice to the people;

(3) Visual interfaces: Deeper involvement, sexier design and intuitive interfaces will arise from better screens, 3D graphics and Virtual Reality;

(4) Complexity: More and more information is available to us, so complexity is dramatically increasing. We need tools to counter this complexity in order to achieve understanding and knowledge;

(5) Mobility: we want to carry our information (and our gadget-toys) with us wherever we are.

Lisbeth writes: "Interesting! Please expand on how and why you chose these five." As I would have written to anyone else claiming this.

And I have no idea! They seem obvious to me, from everything I have seen and read on modern and future media. But how I ended up with that impression, I haven't a clue.

What is worse is that I don't see how I can defend them either. It would indeed demand a sweeping overview over a very large literature, I think.

The very fact that they seem so self-evident is probably a sign of warning. In this view of the world, what are the blind spots?
