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 where this ends up and hopefully not that like that Black Mirror episode with the brain scanning leading to murders.
