What's the most effecient way to preserve your identity, your sentience, and your mobility, beyond normal mortal limits?
Imagine removing all of your body, except for the core neurons in your brain required for experiencing pleasure, sights, sounds, touches, and g-forces.
Imagine using quantum teleportation-based communication systems to offload all of the functions.
You could have a little "worm" of nerves, that was a sentient being, with all the sensor systems made of artificial systems.
So, you have a little carbon-based worm, with life support requirements. Instead of a body, you make a little 8" MEMS spacecraft that flies around silently, moving too fast for ordinary humans to see. For example, a person can't resolve visuals that are faster than 1/60th of a second. If a MEMS disc flies around so that it's not in a visual position longer than 1/60th of a second, it's essentially invisible.
If the worm is physically located inside the disc, then there needs to be a food supply inside the disc.
How many g's can the worm endure? Can the worm be converted to a
"flatworm" by spreading it out on a mounting plate that provides
additional support for g forces?
Would it be possible to locate the worm outside of the craft, yet using quantum telemetry to give the worm all the sensations of flight?
Imagine looking at a worm, and hearing a voice in your head that says
"Hi. I'm a U.S. Air Force pilot, designed at Area 51, with the help
of M.I.T. I really love pulling G's! Unfortunately, my ship is broken down, so I needed to send a distress signal through time, which you are hearing now."
