Wearable technology - here and now?

One thing that's always fascinated me is invisible technology. A solution that is so neat that you don't even have to watch it do it's stuff... it just works. MIT came up with a concept a while back called 'air', not so original you say, but this was a bit - it was the idea that technology was like air - you can't see it. Similarly, they launched a concept called pollen - the idea that information was spread from person to person without needing a network backbone.
This has been adopted in Haiti and disaster areas where the wired infrastructure has literally collapsed. Networks have been built by person-to-person contact through mobile phones, transmitting information over short distances that needs to cover great distances. Yes it's slow, but it gets there. Like everyone is your own personal carrier pigeon.

So, the technology moves on and you end up wearing it and it's everywhere rather than being in your hand. Cute technologies produce fabrics that achieve this.. You can hug someone from a distance by sending them a text. Sensors in the material respond when the message is given to make you feel like you're being hugged. And yes... it's ok to text yourself.
