It would be great if we could
--replace nerves with very fast opticle fibers.
--implement a chip in stratum lucidum, which stores all data like I-card, Credit-card, visa, entry-card (if any), it must also be able to send electromagnetic wave to lock and unlock the door of my car. Sothat I can leave my
Portemonai at home with all its trash.
--I also hate to carry cellphone. To integrate a tiny 7.1 dolby speaker
(must be able to convert dB in Hz duh) in middle ear, and a neumann microphon in a tooth. All wireless. Numpad can be external. Energy source ?? ATP ?? he he, armmm Energy from humid air.
That's it for now. I think by 500 years latter 2 wishes will be reality, the first one will still have lot of bugs.
