FMRI “Mind Reading” Doesn’t Yet Threaten Humanity

visual-image-reconstruction-from-fmri

It is now possible to see what a person is looking at by scanning their brain. The technique, published last November by a team of Japanese neuroscientists, uses FMRI to reconstruct a digital image of the picture entering the eye, albeit at very low resolution and only after hundreds of training runs. Still, it’s an awesome development, and many articles covering this research have called it “mind reading” (1, 2, 3, 4, 5). But it really isn’t, and it’s fun to explore what real “mind reading” would imply.

When I hear “mind reading” I want psychic abilities. I want to be able to know what number you’re thinking of, where you were on the night of March 4th, and what you actually think of my souffle. This is the sort of technology that could be badly misused, as the comments on one blog note:

Am I the only one finding this DEEPLY disturbing? It opens the doors to some of the scariest 1984-style total-control future predictions. Imagine you can’t hide your f#&%!ng MIND!

Fortunately, we’re not there yet. Morover, if we did have the technology to read minds, we’d have much bigger societal issues than privacy to deal with. The existence of “mind reading machines” would imply that we possessed good formal models of the human mind, and that is a can of worms.

Weak AI Will Win

Depending on who you ask, machines taking over the world is either a good thing for humanity or a bad thing. The traditional SciFi script has advanced intelligences replicating through all the networks of the galaxy and having high-bandwidth intellectual conversations about things like the fundamental nature of physics and whether biological life deserves to continue to exist, since it’s such an out-dated evolutionary stage and all. But in his new novel Daemon, and in his talk last night at the Long Now Foundation‘s lecture series, Daniel Suarez argues that it’s not hyper-intelligence at all that we need to be wary of: humanity can lose control of the situation well before the appearance of consciousness on the internet. We’re already delegating our decision making to the machines, specifically the lowly “bots” we use now for a variety of practical online tasks.

The Singularity is Not Near

Blah blah blah singularity blah blah machine AI blah blah the world will undergo a paradigm shift, it’s coming, all bow down before the mighty new technologies that will change humanity forever. The problem I have with talk of the technological singularity is not that it doesn’t make sense, and not that I don’t believe that technological advancement is indeed rapid, accelerating, and world-changing, but that we have somehow invented a symbol of vast but actually rather vague significance. I don’t think the “singularity” is a useful idea. I think it’s a buzzword to some, and a religion to others.

For what makes Futurology (capitalization mine) really, actually different than a belief that something momentous will happen in 2012, when the Mayan calendar wraps around? Not a lot, as far as I can tell. And now it turns out that two religious scholars have concluded exactly the same thing, in a 2008 paper in the Journal of Contemporary Religion:

Futurology-as-religion has charismatic leaders, authoritative texts, mystique, and a fairly complete vision of salvation. Futurology is, in effect, a new religious movement (NRM).
