You guys do know that synaesthesia is a neural condition.
Which is quite rare.
Which is basically bleedout of brain impulses laterally from one part of the brain to the other giving you involuntary misinformation connected to the things that have that bleedout effect.
What you seem to be referring to is
ideasthesia.Which is a different animal.
I would
love the fact that to be a capsuleer you would have to be a more of a delusional bastard than they already are.
The problem for me, with the ship==me approach, has always been the fact that piloting the capsuleer ship is unwieldy. Manual piloting is pretty much hell. There is no such thing as manual targeting or shooting, pretty much every aspect of the control of the ship is automated.
Pick a warping distance.
Pick the orbit distance.
Pick your alignment.
It is impossible for you to point a gun at anything and shoot.
You have to wait for the automated systems of the ship to first get a target lock to the CONCORD authorized target transponder and then activate the automated firing cycle of the weapon of your choice.
That, to me, is far from freedom of full sensory displacement of self to a ship.
Not to mention the psychological ramifications such sensory data alteration would mean.
If a person loses all sensory data from a leg, for example, they might throw that leg, which is still attached to the rest of your body, out of the bed without thinking about the consequences. (I've heard that in the hospitals it is quite common to be picking up people from the floor beside their bed that have this kind of condition.)
Which to a person with regular sensory data of their body seems insane.
Not to mention the fact that as humans we are so connected to our sensory data from our bodies that if we lose a limb, our brains can still keep feeding us that sensory data for years and years after the fact.
Ask any amputee.
Kinesthesia and proprioception, our main ways of experiencing our bodies.
Haptic perception, or the sense of touch, is another completely different animal.
'Feeling the crew of the ship moving' would go to the realm of interoception, which is another different animal altogether.
Humans are much more complex things that I think people believe, because of that complexity they are also very fragile. There is adaptability in the human system but it is very limited. It took us billions of years to evolve into what we are at the moment, just slapping on extra senses and sensory experiences would be completely incomprehensible to our brains and in the worst case scenario would drive us completely insane.
Unless you want to be heavily dosed in Acid all the time and taste colours with your teeth.
Which is cool.
TL:DR
Sensory data and how it is used to experience the world around us is a lot more complex subject than just 'feeling the world around us'.
Our minds are fixed on the sensory data that we normally have and messing with it is a
bad thing.
