It'll be a cold day in hell before Meta gets access to my brainwaves. Good heavens, can you imagine?

I'm glad that, with any luck, I'll be dead before this kind of thing is commonplace.

Interesting -- really excited for the future of human-brain interfaces and just in general more interface exploration enabled by large transformers. I'm already very excited by voice, although wish I could get something akin to the subvoc common in scifi novels. Seems like it would be an easier path than human-brain and would allow me to use voice models in public.

As an aside, disappointed by the very low quality of comments on this article here.

So attended an interesting talk a couple years ago: - fMRI and/or brain implants are the best to figure out brain waves - but they are expensive or invasive - EEG is a lot cheaper and easier but not as precise - BUT what if you used LLMs to analyze EEG data taken at the same time as brain implants etc The answer seemed to be that "yes, you can get better than traditional EEG data using EEG + LLMs". Curious to see whe…

Piramidal was doing that last I checked: https://techcrunch.com/2024/08/23/piramidals-foundation-mode...

Any minute: wear it permanently to sell training data on LLMs. Take an audited IQ test to negotiate your rate. Better than text-stripping the internet - this thing will soon be pulling the logits as well.

Now the remaining problem is to make Magnetoencephalography devices affordable and not insanely huge.

From a few days ago, uses ultrasound. https://news.ycombinator.com/item?id=48685558

The ultrasound technique there is more like MRI, static imaging, not measuring dynamic electrical signals. Also, regardless of static vs moving, all of this hinges on massive relatively expensive devices (ultrasound is never going to be dirt cheap or miniaturized compared to a smartwatch or even a VR headset) and for the subject to remain perfectly still and probably go through regular calibration sequences. All for Also, in the Meta result here, "while actively typing" is actually quite different than passive mind reading because the motor cortex sits nicely near the top surface of the skull, and the muscle memory from past typing makes for a nice well formed signal to measure and classify. It's the same trick over and over since the Brown BrainGate days where you can have people perform or imagine movements and get a decent but not good classification result, and it never gets much better after that trick is exploited. Project dies, VCs and grant writers forget or never appreciated the effect, time goes by, a grad student or corporate research lackey rediscovers it, media puts out an article claiming mind reading is here, and the cycle repeats...

Coming soon to a Meta office near you: brain-scanning to make sure employees are focused, happy, and productive! There are no layoffs in Ba Sing Se.

If this happens, I'll be listening to music with the most annoying lyrics on repeat.
