The technology of hardware will continue to evolve toward devices that do not resemble their function or purpose.

Children will play with toys that, unbeknownst to them, use sensors to rate levels of contamination and then sanitize their hands and faces as appropriate. Mobile devices will overlay real-time virtual patterns onto real-world fields of view to anticipate everything from danger to directions.

Sometimes, it seems like humanity wants to use science to move the world ever closer to one that resembles a sort of science fantasy:  using computers to manipulate virtual realities in mid air, wearing invisible second skins as a personal force field to traverse inhospitable terrains, etc.

I can only imagine the kinds of stories the people in that future will tell!
