I've been fascinated by this topic since a couple decades ago, when I participated in a research study involving EEG and word recognition. Progress seems to be slow but steady, with applications getting more accurate and practical.

Your point about invasive implants being impractical for commercial use made me wonder.. I searched the first phrase that popped into my head, "Non-invasive Brain-Computer Interface". Looks like there's promising research on significantly improving sensitivity/resolution of EEG singals.

- Noninvasive neuroimaging enhances continuous neural tracking for robotic device control - https://robotics.sciencemag.org/content/4/31/eaaw6844

Still, your prediction of "likely decades" sounds realistic. I'm hoping for an affordable, non-invasive brain-computer interface to be as widely used as the keyboard, mouse, or microphone.

I don't think this is the first ever non-invasive bci. I recall decades ago there was a BCI where you could control between left and right literally by activating the appropriate hemisphere and triggering a relative potentiometer.

Extremely crude, but it worked. IIRC the instructions were "to go left, think 'go left'"; "to go right, relax". After some number of sessions (I think I remember it being "a lot") the user's brain would automatically do the correct thing.
