they've been bragging about how good that neural wristband is for years. It's strange they haven't ventured to make a smartwatch with it. Maybe because Zuck has been so focused on AR/VR
And if you really get into them, maybe it's worth spending the time to learn chords instead, like for a court stenographer?
IMHO the tell on why there's a delay is the original comment expressing wonderment at Zuckerberg demonstrating 30 WPM.
i.e. it sucks.
It's nice technology, engineering, glad they had the courage, sure its useful for its purpose.
However, in practice, humans being humans, the odds I regularly put on a glove, to get 30 WPM, on my glasses computer...very low.
(also, looking back at the original comment...neural interface? wtf? It's not neural...)
