The redneck strike again.

The same thing happen with human consciousness.
For a million of years it has moved very very slow.
In the last 15000 years the speed has improve and in the last
few thousand years has gone even faster
But now at every step it goes faster and faster.

How are you defining consciousness? How are humans as a species more conscious today when we still have wars, religions, ridiculous superstitions and have exchanged fairy abductions for alien abductions etc.? The things that drove our ancestors still drive us today.

You just look at the technological progress.
Almost no progress until few hundred years ago but now
is going very fast and it will go even faster in the future.

What does consciousness have to do with technological progress? If we're so superior to people in the past, why has our species spent so many resources developing and making more efficient ways of killing other humans? Then there's the fact that our rapid technological progress in the past few hundred years has had a devastating effect on the planet and other species of animals.

Let's say that Ötzi's nervous system really was subtly different to ours and those tattoo marks prove that there was a form of acupuncture treatment back then. His health problems, which were revealed by the studies, show that the treatment didn't work. This goes against your idea that acupuncture was more effective a few thousand years ago because people had different nervous systems.
