Many folks who are working with the Singularity Institute at Stanford University are busy considering future concepts, schemes, innovations, inventions to see that technological advancement and forward progression of the species. It is wise that we do this to protect us from future calamity or population collapse. It also makes sense to consider ways to save yourself against the worst predictions of the doom and gloomers just in case, even if you don't believe in conspiracy theories. Okay so let's talk shall we?
Recently I've been reading about many technologies coming to fruition, as mankind learns more and more through research. In the nano-tech field it was discovered that carbon nanotubes are quite suited for emitting holographic light. They are also very good at capturing light and manipulating photons. This got me thinking that it is perhaps possible to build a human brain using stem cells and growing them on a carbon nanotube lattice, where the carbon nanotubes also have another inert element attached so that the enzymes in the blood do not dissolve the carbon nanotubes.
Since the human body is made up of carbon, the carbon nanotube structures will not cause any problems in the human bio system. The brain structure, neurons, will weave in and out of this lattice, and the structure will also be able to collect the frequency and light transmissions from the brain. This puts all the activity within the brain on a 3-D grid. Therefore it would be perfect for computer human brain interface. Now then, before you call me crazy think about what I just said, how it might work, and ask yourself if this could be a concept worthy for the future.
If we have stem cells, and we provide nutrients, the brain will form around the lattice in the shape of our choosing, and at first we will wish to use the same basic shape as a current human brain. By either intercepting the signals or reading them as they flow by, we could be reading the brain's thoughts and transferring them into ones and zeros. Meanwhile, we can also interface with the brain and get information stimulating neurons with electronic pulses in specific areas once an individual's brain once mapped - this means we would have two way communication.
You might think this sounds too far-fetched, but maybe if you do a little extra reading, and cross pollinate all the ideas I've been discussing, you will see that we are well on our way to make something like this happen. Please consider all this and think on it.
