This doesn't really answer the question I intended.
I am wondering why we would have been built with different sensitivities. How is it beneficial to the machine to give people different capacities to feel and and therefore act on those feelings.
This is a very good question. First of all, there is no machine giving people capacities. We are not built
with different sensitivities. There are essentially two paths in evolution. One path is the evolution of the VR PMR such as DNA, culture, language, beliefs, etc. all part of the fluidity of the rule set. The other is the evolution of consciousness, our purpose. We (IUOC) create our sensitivities, our reality a lifetime at a time, with a plan to optimize the profitability of the experience.
It is not a case of peopel ignoring and then gaining increasing intense feedback but simply some people are built with more capacity than others by default.
Yes, some people are born with more capacity than others. This is evolution.
For example it is well documented that a high proportion of the population are psychopathic i.e. unable to empathise or feel. This would be highly detrimental to their ability to gain higher quality consciousness. So why programme people that way and make it harder?
Emotional intelligence is learned through experience. We are here to learn. We are not programmed. We create. We make choices based on our capacity.
