Reply to comment by TwistDirect in New Technique For Decoding People's Thoughts Can Now Be Done From a Distance by fungussa

I mean, right now the machine can tell if you're paying attention to a pre-selected, silent film by watching the visual cortex.

We're still a long way from reading any coherent thought.

Not too far.

Pretty well can mean just identifying vague topic, like love, nature, fear or mean a 1000 page detailed description.

Pretty well it means nothing

Yeah, you’re right, it’s a preprint so waiting for the peer-review.

That's not what I've said, but thanks for assuming I'm a careful person rather than just argumentative.

You’re welcome! It’s selfish altruism though. You may have been just argumentative yet I benefit on average more from my assumption than its alternatives.

Selfish altruism is just something that works for everyone. If you’re trying to do something good, how wonderful for it to feel good for you as well. I’ve stopped seeing “no true altruism” as a depressing thing that means we are all selfish, but instead as just a really cool extra gift.

Remember, that dumbass from Google thought AI was here.

I do and I’m skeptical of these results also (see my comment above). The claims and reported results are significant because their non-invasive nature and accuracy will catch the interest of industry quickly and where capital flows, innovation sometimes follows. Marketers using this to fine tune advertising targeting is just one concerning application.

Eventually they will be able to interact with every single neuron in your brain

Yeah, no.

Not with this technique.

To get every neuron you'd need a very invasive implant.

Hell, this technique can be ruined by just moving your head.

It also needs hours of training data, pre-selected training data. So while this is kind of cool, it's not mind reading, and it's not coherent thoughts.

You dont need an implant just very sophisticated software your brain is one big wireless reciever you need extremely sophisticated software and a modern high quality broad spectrum microwave radio transciever

The barrier is the software not necessarily the hardware

Also they are working on AI which trains itself automatically

By reading the article, I got the feeling that they could re-create the stories they heard. Not the exact wordings, but they still get the story right.

Have I misunderstood something? Isn't that huge?

From my understanding, they could only track the story as the people were in the MRI listening to it. And it took hours of training data before they could do that.
