> any signal source can become a sense.

A new sense?

That's unheard of. We can map any signal to an existing sense, but not create a new sense/sensation.

That would be one of the most relevant developments in human history and a gigantic step towards cracking the whole qualia problem.

If one's eyes were replaced with the signal generator, I believe the parts of brain that process vision normally could adapt to this almost as well aa if a "new" sense had evolved. Full adaptation may require that it's done as a child or use of some drugs / theraphy. Perhaps trasncranial stimulation could be used in one form of adaptation theraphy.

I suppose the extreme version of the parent comment's vision would be to develop entirely new neurological circuits that can process, interpret, and integrate some arbitrary new source of data in the world. I agree that that's kind of unimaginable now, but give infinite monkeys infinite typewriters and one of them will probably hook up the company's sales data to a new section of cortex just to see what would happen.

I read a more interesting takeaway, perhaps: that we can — and do — develop new "senses" for any given signal we can perceive. A possibly-shoddy example of this is what social media does to us: the social networks provided everyone with a novel social sense, and indeed everyone who uses social networks perceive and attenuate to that sense in different ways.

This has practical implications: given that we don't have infinite cognitive capacity or even much moment-to-moment bandwidth, we should be careful about which of these digital senses have our attention.

There're obvious links here to "augcog" (augmented cognition; [1]), but also I feel like Ackoff's five assumptions about "management misinformation systems" are relevant somehow[2].

Interesting to think about!
