Not OP, but Ttat article's use of the word "implant" implies a much more invasive device, which means a way better signal. Additionally, the output, while still complex, is far from the level of decoding of thought presented here. Thus, while still impressive, it is less of a leap from existing technology, and much more within the realm of what we know is very much possible.
