Computers that don't need electronics

What is a vertical cavity quantum switch?

Jin sees a great deal of potential for using an all-optical switch for Internet routers. He points out that energy consumption around the world is massive from Internet routers: “One of the major problems of the conventional Internet router is that it employs a optics-electronics-optics (O/E/O) interface, which requires additional energy to exchange the information carried by photons to electrons then go back to photons. To Use an all-optical switch, which means a light beam directly controlled by another light beam, could possibly cut off the additional energy consumption due to the O/E/O interface.” 

There is also potential to use all-optical switches to help more effectively reduce the size of computers. “Scaling down computer systems which can cause extra delay in short electronic wires, which further blocks the data transfer rate,” Jin explains. “To do the interconnection using optics would possibly avoid the delay and distortion in the conventional electrical interconnection.” Without the some of the drawbacks of electronics-based computing, an all-optical switch could ultimately overcome the current bottleneck of electronic chips.

Computers and other technological devices will eventually become so small that they can be easily intertwined with biology and you couldn't even see it.  What if such technology has already been developed?  This would help explain some things that otherwise can't be explained right now.

For an example, this is my own explanation for what bigfoot is -- not a biological entity per se, but a biological construction using methods advanced far beyond our own.

Anything walking around in the woods that appears to be alive but has eyes that light up independently of a reflective source is either a) your imagination running away with you, or b) a construction of some sort.

If that's true, the question isn't what is a bigfoot or does it exist, but who owns them?

Never forget that we arose on this planet about a billion years after life was possible.  Plenty of time for someone somewhere to get quite a head-start.

LATER:  Speaking of bigfoot, if you ever wanted to see a comprehensive list of bigfoot on film, here's your place to do it.
