It is an interesting topic. I am reminded of the amazing philosophy of Alan Watts, who in 1966 (

) predicted this of the future:
All information will come in by superrealistic television and other electronic devices as yet in the planning stage or barely imagined. In one way
this will enable the individual to extend himself anywhere without moving his body—even to distant regions of space. But this will be a new kind of
individual—an individual with a colossal external nervous system reaching out and out into infinity. And this electronic nervous system will be so
interconnected that all individuals plugged in will tend to share the same thoughts, the same feelings, and the same experiences. There may be
specialized types, just as there are specialized cells and organs in our bodies. For the tendency will be for all individuals to coalesce into a
single bioelectronic body.
Taken from his book
The Book on the Taboo Against Knowing Who You Are.
IMO the internet, and the direction it is heading fits this description quite accurately. As populations rise, technology increases and current trends
continue, we will be doing more and more daily tasks and living online which in the past would be done offline (shopping, socializing, working,
exploring, etc). With everybody interconnected and a merging of biology and technology I don't think it's that much of a leap to go from something
like individual living cells in a brain communicating with each other to create a consciousness to the same thing on the next higher scale.
