Deep Learning techniques are making it easier to decode signals from inside our bodies and minds, accelerating Brain-Computer Interfaces by threefold, with complete accuracy.
Internet bandwidth follows a variant of Moore's law, Nielsen's Law, increasing by 50% year-on-year.
Extrapolating from prior developments in this space going back to the 1970s, I posit that we can expect similar increases in bandwidth between bodies/brains and computers going forward, for both unidirectional and bidirectional interfaces.
Wearables similar to Airpods will eventually replace contemporary tiara-style sensors, much as those are in the process of replacing cap-and-saline devices today. When it becomes unobtrusive, such interfaces for neuro-dictation will cross to mainstream adoption.
