I am all for dystopia; already with VR/XR/etc. you can probably infer a lot, especially once they start (or have done already?) scanning retina movements and such. But still: stimuli is a one thing and mind-reading (thought control?) is another.

BCI is literal mind-reading: when the thought goes ping, it shows up on the wire.

The current limitation is that the number of sense-wires we can put on a BCI implant is a factor of ~2^30 smaller than the number of synapses in a human brain.
