Did you actually watch the whole video? The entire point of that video was that input channels (senses) can be repurposed to completely different uses, and the the brain's processing functions are generally undifferentiated. I suppose in the most pedantic sense it is the "same" sense, but when someone starts "feeling" the stock market or "feeling" a factory, it rather strains the language to say they are just "touching" it, or whatever. And certainly someday there will be processes that take an existing brain and grow a new input channel for a direct feed into our blobs of undifferentiated processing function.
