One, Zuck probably practiced for days for this moment and just managed 30 words per minute (which is slow, 1 word per two seconds is really bad).

Two, just try doing this now, moving your hand around like its writing with a pen and see how it feels (without holding a pen). It's super uncomfortable and feels really weird and also looks really weird.

People are really sensitive to looking weird and feeling weird and especially being singled out for being weird or looking weird. Also, there is a huge subset of society now who will not buy anything made by Meta. I think this product is doomed to failure honestly. Happy to eat my words when I see the subway filled with people wearing this dystopian specs.
