Well, yes, but specific simulation required by your employer is different to spending every waking hour pretending you'rean airline pilot (or a WWII ace, or an astronaut in some cases)

Virtuality is something that is going to be an increasing part of human society as long as civilisation can support a technological culture. In fact, we are experiencing virtual reality straight out of the biological box. Research into vision sugggests that colour is a fabrication of our brain. there is no intrinsic quality of light that actually colours anything. It's just that our brains interpret the various wavelengths of light into visual categories. That's something we learn to do as soon as we can see, and bizarrely our ability to interpret colour is linked to our ability to describe it - so language and colour recognition are linked, although biologically blue and yellow are hardwired in by evolution for some reason.

That's so true. Actually, the difference between "reality" and "perception" is matter of discussion since centuries, both for philosophes and scientists. From the so-called "mith of the cave", to Heisenberg's indetermination principle, men of knowledge are well aware that nothing grants that what we "see" is actually what there "is" and, furthemore, the way we observe reality affects not only our perception, but even reality itself, thus making a pure, neutral, absolute concept of reality a chimera.

Such topics risk to open an abyss of philosophy! ;dd :mrgreen:
