The only problem with making phones smaller is that it eventually makes them hard to operate. But the interfaces imagined here show that we can definitely go small, thinner, lighter, without becoming clumsy.

Eventually, the speaker and microphone will probably become something like a little dot that you press on next to your mouth and ear. (Eventually, they will be implanted, but that’s got its own set of cultural baggage to deal with.)

I applaud the creators of this presentation. Keep it up!
