But seriously, telepathy is a solved problem. Unfortunately, it's a solved problem the same way jetpacks are a solved problem - you can't afford it, you don't know how to use it, and for practical reasons it's not all that useful.
No it isn't. We can monitor and stimulate nerves. You can send impulses like muscle controls or other stimulii external to the brain, but anything as far as thoughts go is farther in the future than strong AI. Thoughts and such exist on a higher level than the neurons; that is to say, a pattern of neuronal activity in one brain will not translate to the same thought if copied to a different brain. Being able to both fully decode and then re-encode something in the brain on the level required for anything useful, the symbolic level, requires A: an understanding of neurobiology far exceeding that required to create strong AI, and B: a way of noninvasively and repeatedly scanning a living brain for a complete mapping of thought process. That's damn near impossible, as it requires analyzing trillions of connections, their strengths, their full effects on the nerve cells they are attached to, etc; and it must be redone at the very least once a month, if not once a day or less, as the mapping changes as we form new memories and such. Also note that in doing such a mapping, you have just done the equivalent of uploading your consciousness to the computer in the form of an AI. And many, if not a large majority of the time, even the higher level symbolic representations can not be re-encoded in the framework of the second individual simply because of subtle difference in their thought processes.
There's so much wrong with this that I'm not going to bother going into it, but instead I'm going to dismiss it by pointing out the obvious: you're apparently using some particular definition of "telepathy" that is neither useful nor at all relevant to this discussion. There's no need to "understand" the brain, or convert thoughts, or decode anything. There's no need to analyze trillions of connections, or "map thought processes" or any of the stuff you're talking about at all.
If you can simply capture words from the verbal portion of the brain, transmit them via wireless connection and send them via vintage 1960s style
email and allow others to receive email via that same wireless network and receive it in the audio and/or language processing centers of their brain...viola, you have telepathy.
The critical portion of that was already linked in one of my posts a few pages back in a video showing a guy wearing a strap on headpiece (no implant at all) that allowed him to type by thinking about letters. Give two people those headsets, hook them up to wireless internet and let them talk via any kind of instant messenger protocol and once again...viola, you have telepathy.
While you're at it, go watch the
also previously linked videos showing brain to computer interfaces extracting what the visual cortex is perceiving to digital video. Send that via the same method.
If I can look at hot chicks on the beach, and stream a video of what I'm seeing along with text and/or speech and/or text-to-speech saying "wow she's hot!" to my buddy in another state in real time and have him receive it...all with neither of us moving a muscle, or touching any kind of external device like a computer/phone/etc...as far as I'm concerned that qualifies as telepathy.
I don't even know what the point is of all this other stuff you're talking about.
One final point that it I hesitate to mention because you're liable to read it and forget about all of the above and focus on it to the exclusion of all else: Data is data.
Understanding or "mapping" data is irrelevant. So long as you have a means of sending and receiving data the actual
nature of the data is not very important, because a very simple learning process will allow humans to do the necessary processing.
For example...no, wait. Giving
an example is actually kind of redundant, because
all possible examples would demonstrate this. Right now you're looking at little squiggly lines of light and dark on a screen, and yet
you've learned to process those squiggles as things like words, sounds, and concepts. There is no fundamental relationship between these squiggles and the ideas going through your head as you look at them. It is purely a learned means of communication.
If I can send something to your brain and you can receive it and send something back...
we are capable of telepathy. It doesn't really matter
what it is you're sending. Raw sound, images, video, heat maps, morse code, anything. Through practice you would be able to learn to use that medium for communication, just like you've learned to press sequences of buttons that have nothing to do with your thoughts to make squiggly lines that have nothing to do with your thoughts...yet nevertheless are able to communicate your thoughts. Or, just like you're able to vibrate your vocal chords in ways that have nothing to do with you thoughts to make sounds that have nothing to do with your thoughts...yet nevertheless are able to communicate your thoughts.
It is no different.
