look , apple , Google and that companies as big as them , have enough projects , science and tech. to do with next (at least) 10 years .. ex: apple is turned from company which produce new tech devices for users to the one who really care about us , like how to deal with life , how to give things the meaning and so on ( actually it got that step when their heart back again ( JOBS) )
also Google has loon internet to do next years beside the other big things they are doing now.
so wherever we look at new generation of mobiles without wires or without batteries or loons to provide internet to the whole earth , we found our selves just impressed about what they do.
trust me , they knew us much than us.
