Speaking of BCI, there are startups intent on implanting thousands of nanoscale sensors directly in the brain to gather copious amounts of data directly.
"You are seeing this advert because we detected that you thought about the Budwesier 'Wassup!' advert that aired 22 years ago and it increased dopamine uptake by 3.7%"
I wouldn't call it "copious amounts of data directly" you still gotta train yourself to use it, and the interface itself should train itself to recognize it.
It might be enough to make people walk again though.
