It's coming! It is coming! Designing behaviour is just around the corner.
Look - now it's toys, then it'll be consumer electronics, then it'll be everything.
What do I mean by that? Don't know, but here's the really crude stab of someone who's NOT A DESIGNER IN ANY WAY.
At the moment physical products have functions - what they do. And they have characters or personalities - how they feel.
And some things, a few things, have behaviours - ways of performing those functions that step outside the strictly functional. They convey personality through actions, not just through appearance and materials.
And, crucially, those behaviours can change in ways that the functions and the materials can't. Because the behaviours are in the software, not the hardware.
So the Neato feels a bit more human than the Roomba because it behaves a bit more humanly - but a bit of hacking or tweaking and everything could reverse.
The horrible extreme will of course be the backup personalities of the Sirius Cybernetic Corporation, the brilliant extreme will be the toaster/transformer and the mundane middle will be a telly that puts the lights on if you get too scared by Dr Who. Or something.
Anyway. That's not important. 30 BEHAVIOURS! How many do you have?
