Don't know if physorg has caught this yet, so....

I just hope we are mature enough to be in control of such amazing technologies.

Although I remain optimistic especially for future medical use and further exploration of such scales.

I need to know more!

Therein lies the problem, as 'hoping' is not 'doing'! There is an equal amount of work to be done in understanding the implications and complications involved.

I am not necessarily opposed to this motion, but it would be nice to see some balance!

Impressive

Still far fetched though.
But if we exist in say fifty years having a technological civilization like now.
we'll see.

wow

best link so far

Makes us fragile things look more like the 'missing link' everyday, doesn't it?

How quickly we are able to convert to 'aliens', once the 'method' is discovered!

This is representative of one of the basic hurdles in creating computing machines that themselves can invent technology beyond human ability. The human brain is remarkable in it's synergistic thought processes because of massive parallelism, something that artificial computing hasn't achieved yet. These first baby steps are the harbingers of something truly beyond our imagination: artificial imagination, if I may put it romantically. In theory, successfully marrying massive parallelism to the computing speed and 0% loss of data retention/retrieval will open the door to possibilities known best by today's scientific poets - the authors of science fiction itself. Articles like this must be extremely exciting for them; more than they can be for most of us. The days ahead of us shine bright. We will get through, and see them. The frontier will never cease to be, and we will never stop following it.

I think it is also possible to see this not as necessarily 'artificial', but really as an extension of the previous thing! Technology is evolving, and it can only do so because it is Real, it Exists, it is actual and happening.

There is such an aspect as 'rapid evolution'. This is because Evolution is not something that 'travels at a constant speed'. Thus, certain aspects of it can move extremely 'slowly' and others extremely 'quickly'. A still, calm day and a tornado are both aspects of the phenomenon we call 'weather'.

So, as the environment changes, so do all of the 'parts' that go to make it a 'whole thing'.

Thus it is with 'artificial intelligence'. It quite simply emerges from the 'ashes' that are us. In order to stop being afraid of such things, we must stop being afraid of ourselves, firstly, as the 'programmers' of the foundation for future thinking. While we are still warring, self-polluting maniacs, this will be the foundation for that which we pass on to our next levels of 'Self', whatever 'shapes' they may form themselves into.

This is very interesting. I had thought the story about the link to the brain through the brain stem was interesting out of Australia back in the late 90's. I will love to see where this technology is taking us and what we might learn. The math behind it is somewhat difficult, but with better technology along the way we will be able to process that at quicker speeds. I still haven't found my computer with a terahertz processor and terabits of ram in it yet though I am hopeful that the computer catches up to the brain. The did get a system to run 1.3 terahertz though that's still not quite up to the capacity of the brain. That is why i have such an interest in the gluon field and it's interactions and the vectoring out of that stuff is just simple geometry that takes a lot of processor time.

In addition...

This is the half/hoaxed, 'AI Eidolon 'The Last Prophet''.
Not entirely real but offers some interesting logical Sci-Fi insights to a possible future scenario.

AI is slowdowning exponentinaly, biology is trilions and bilions times more dificult than singularity of moushit

Slowdowning?, Moushit?

But yes biology is extremely complicated. AI is in it's infancy, still mostly Sci-fi.

However, as we learn more about our biology, evolution, environment, mind etc the closer we get to unraveling the secrets of intelligence.

Once we begin to see past the myths and fallacies regarding the mind and consciousness
we will have a better idea of how complex it all really is.

What you have to bear in mind is that you are a biologist. Your brain and body are actually performing all the things that biologists that study the Human body are only beginning to understand.

There is so much information, calculations, chemistry etc etc that your brain is constantly managing, that if you were conscious of it and had to think about it, you would probably die of Human error. Even the best biologists in the world ever, could not consciously perform all the tasks that your sub-conscious or un-conscious brain is performing. Ironically we probably know more about these automated functions and how they work and what they're doing than we do about consciousness.

I'm personally trying to figure out which is more complicated, however AI or Robots whatever bypass much of this problem as we already know how to build computers that can perform automated tasks, we just need a better understanding of what consciousness is. How do we create a brain that does not need to worry about what it's doing and just do it. That's what we do. How do we create awareness of external environments. It is complicated but then Reality often is.

Sciencists can't precisly simulate C. elegant nematode, which has only 302 neurons. And I think this is becouse not the imperfect neurons and synapses simulation (synapses understanding is incomplete), but formation 3D structure of neurons and axons, dentrids, synapses interaction, becouse there is function physical very dificult, which describes how, in what intensity and soever synapses must connect with dentrids, there is much more physics than in some turbulence of whater or air. There is friction then them connected. Computer unable simulate brain, becouse there is too much phisics needed simulated for understand how brain map is builded. Nature working in such process, that you can see whole thing, but can't analyse and understand processes of each part and so I think that if all silicon on earth you will turn into chips, then still will be don't enough power to simulate single brain and it's map construction... Becouse there is a lot of physics, between neurons/axons/sinpses interaction and this physics very hardly used in phormation of brains. And so to phorm brain map need simulate all physics. Which is too hard. Moore laws decain is over and it's exponentionaly slowing down. There is now new law, according to which number of transistors each 18 mounts increase fewer and fewer times: 2 times, 1.5, times, 1.25 times, 1.125 times, 1.0625 times and so on. when years goes to infinity, number of transistors increases goes to 1. So we will never be able to simulate human brain or even rat brain. Another very dificult problem is to create body with receptors and motorical functions and so on. Robots capability never will be such good as animal. So I think AI, nuclear fusion and quantum computing more realated to art than to sciencie. Current neural networks can recognise some objects like ball, maybe faces, very badly language, but they making it machinery, maybe no, but still to conciounes is very long way, which will never be able for computer, becouse it is human creation and not creation from all possible nature variables. And human will never do beter certain things than nature...

But that's just it, we may not need to re-create the brain because we already have them in abundance.

Moore's law is only limited by our current technology. Just think back to when a comparatively simple computer was the size of a room. If they had projected Moore's law to that technology, they may have predicted that your average home computer would have to be the size of a building and dismissed the idea as Sci-fi. Convergent breakthroughs in miniaturization of similar technology allowed for even more computation power to be condensed into a much smaller space. Further advances allow for the interconectivity of those computers and Networks are born.
A future projection of a Network could be condensed further perhaps.

Moore's law has difficulty predicting certain factors. Ideas are often way ahead of the technology we have at our disposal ie; Virtual Reality, which was an interesting idea which looked terrible and didn't quite match up to it's purpose and essentially boiled down to controlling items limited within cyberspace, however science and other related fields are learning how to create better, smaller computer controlled devices that exist in the real World, so don't be surprised if at sometime in the future we see a resurgence of this idea powered by more capable technology, Nanotechnology perhaps?. The potential benefits in medicine are promising. It's this type of convergence in materials, power source, ideas, scale, need etc that are difficult to predict.

Biological computers could sidestep Moore's law altogether by growing similarly to a real brain. But that's a long reach from now.

Never say never in regards to Human endeavor!

Kind regards
