The ideas have always been there, it’s just a bottle neck on cheap electronics and people figuring out the foundation technology. I can’t think of to many tech advancements that have surprised me; that’s not too say they aren’t impressive, but just about anything we can imagine is possible.

The main thing I don’t expect to see is useful and reliable brain/electronics interfaces. I think biology is too unique for an of the shelf product to be possible, which means it’s too hard to make a profitable product.
