@marcbeaupre You need to generate 3-7T of magnetic field strength, which requires a large magnet, lots of power, and helium cooling. I dunno what the physical limits are on magnet size for field generation; also power consumption/dissipation seem like big issues

As a neuroscientist imma call bullshit on this. All these "mind reading" techniques rely on an fmri scanner: a multimillion dollar, 10000lb+ machine that requires a purpose-built facility and you have to lie perfectly still in it for it to work. Nobody's stealing your thoughts

@leavittron Yeah but you know things only get better. Every electronic technology was once huge. Better and smaller is inevitable. I don’t need to know anything about this tech specifically to say this. Timetable though? No idea.

@marcbeaupre Overall, I suspect miniaturization would require a massive breakthrough in materials science. The tech has already been around for 30+ years. I'd sooner bet on a different brain imaging modality than fmri miniaturization, but I'm also not an fmri expert

@leavittron @marcbeaupre There is another way to directly measure the very weak magnetic field generated by neural activities, hope you are aware of that. No need of any big magnet, big power and helium. And yeah, those give you much faster signals than blood oxygenation

@hb_cell @marcbeaupre Sure! Which one are you referring to?

@leavittron @marcbeaupre @egregirls it gives whole new meaning to “we are going to put you into the machine”
