According to the BBC, telepathy is here, sort of. Human brain waves can be read by machines, then transmitted by machines to other human brains, which can perceive them. At the moment, they are perceived only as light, not the original thoughts that they were. Before we get too excited, the researchers say they think the technology will eventually allow perception of the original thoughts, but not in our current lifetime. I can see another implication though – if brain patterns are already being read into computers, we will eventually figure out how to have computers interpret them. Assuming progress in computing power continues to be exponential or super-exponential, I wouldn’t be so sure that we won’t see this relatively soon. Lots of exciting, and scary, implications, of course.
