(..wife Joan is the better SF writer - "Eyes of Amber" a classic which probably stimulated interest in Titan)
VV reckons that faster machines will, by 2025?, take off, smarter than humans and ever smarter,
I reckon he's wrong,.... What is an individual?"
..outside of biology, there are no individuals, only stuff.
... Pictures from Venus, Mars, Moon, Titan etc all hava a certain similarity.
A bunch of rocks lying about. For millions of years, maybe....
I maintain that these chunks are not individuals.
Rover drivers gave names to some particular rocks on Mars, so they could talk about them. But they remain chunks.
The names are in the minds of people.
Only biological systems are individuals.
Humans project individuality, personality, onto thunderbolts, and the overall origin of stuff.
Aside: its odd to realise that no new living cell has appeared on Earth for Billions of years.
As far as we know every extant cell results from budding off an existing cell. Same applies to mitochondria and chloroplasts.
For all the claims about DNA, it doesnt make new cells, it merely provides templates for enzymes to extend existing cells, which bud themselves off. DNA does not make life, it just swells it.
Maybe alien cells have arrived from space every 10MY or so, but none have out-competed current life bacteria rule
Faster computers are just that.. faster computers. The energy requirements are arduous . We might simulate a bee or a cockroach, but we currently are way off from powering such mobile gadgets on breadcrumbs or nectar.
Nano tech fans postulate nano-factories. Well,.... show me a normal size factory making, ...say, clothes-pegs, which needs no Human intervention. Not just very little intervention, but none at all. There is No such factory.
It has been said: every factory assumes an entire technological supply and support society.
Only biological systems feel pain, or pleasure.
The deepest operation is comparison.
Krishnamurti understood "I think one of the causes of fear is comparison. You know what `comparison' is? To compare you with somebody else, to compare you with a clever boy, or to compare you with a dull boy, "
comparison is deeper than desire, it is the foundation of desire.
Krishnamurti the deeper mind engineer than Buddha
Joshu said "Who is your neighbour?"
Buddha said "What is desire?"
Krishnamurti said "Can you live a life without comparison?"
The first bacteria with a flagella, had a memory. It would spin and tumble less where the sugars were more concentrated. Memory in time, before comparsison in space. Desire invented simulaneously with memory, comparison and motility.
None of these are inherent in a rock, or a computer. We can simulate desire, with a pleasure/sugar level accumulator possibly, but set the acumulator full and the machine will cease from wandering.
biology grows, swells, buds, grows.
Machines are constructed.
Life longs to reproduce and disperse.
A bee shakes with passion with the memory of a clump of blossoms.
An imitation bee might seek out a neck to sting, but only at the behest of its builder
no fast processor can care. nor desire. Not desire to conquer the world, travel to the ends of the world, dominate, reproduce. Only we can set their desire accumulators, low or high.
A very fast processor would sit idle until told what to calculate.
Higher cognition requires anxiety?
With complicated memory, comes the pressure to attain a better situation, the pressure to do something, anything
"get me out of this place" " a bunch of large social mammals are about to steal my potatoes attack/criticise/evict/ me"
"there must be somewhere better than this"
Can a machine feel anxiety? wold a super-smart machine be super-smart at getting a supply of Xanax?
How to give a box the illusion that its existence is important?
Rather easier to instill in an assemblage of leaky membrane water-based cells, with a billion year pedigree, and loaded with pain receptors.
Eight days before Christmas Day 2005, neurologist Oliver Sacks — author of Awakenings (1973), The Man Who Mistook His Wife for a Hat (1985) and other popular collections of case histories — went to the movies. Sitting in the dark theatre, he noticed an incandescent flickering to his left, which he took to be the first signs of a migraine.

Recently I have noticed flickering patterns in my blind spot. On testing, the blind spot is rather large.
Damn my eyes if I cant lay my hands on a decent ball of opium...
