Sock Technology? Why not?

Okay, here's my point. We use technology for all kinds of things: RFID tags, nanotechnology. As I spent half of another Sunday doing laundry, the question came to me: Why can't socks match themselves? Really. There should be some sort of nanotechnology or something that could help the average person with this plight. At the flick of a switch, once the laundry is done, the socks should find each other so they may be folded into proper pairs. If that is not possible, then perhaps at least the ones from the same pack (as they were bought at the store) could be implanted with a small light of some sort that would glow red, green, yellow, blue, etc. based on the pack from which they came. If you are like me and buy socks in 5 or 6 packs, it does not necessarily matter that each of those socks is paired with the same sock each and every time. But, it does matter that socks from a pack you bought last week not get matched with socks from a pack you bought six months ago. Even though they may have started their lives as exactly the same socks, the older ones are changed drastically by their travels through time (not to mention the agitator, spin cycle, and dryer). They are but a vision of their former sock-selves. They wear differently, and it is not comfortable to wear a new sock with an old sock. It's not right, and it's not the way apparel-life was meant to be.
So, someone, please invent this beautiful world for me... where socks match themselves; or at least one where socks can tell you with which possible mates they may work well. There does not have to be 29 dimensions of compatibility. Let's not make this more difficult than it has to be. I just want more time in my Sunday afternoon, and sock technology will provide that to me!
Thanks,BJ
