Most people speak at about 150 wpm, but very few can type that fast. But reading and gesturing are fast, which is what TFA is about, combining reading and gesturing with speech.
I usually convey the same meaning with 80wpm typing. Makes it faster to read too
Maybe I’m just slightly adhd – listening to people talk drives my crazy. Get to the point! Much easier if they type it out
People have so many verbal tics and filler words too. Anthropic’s Dario says “you know” after every third word, for example.
Or they meander around unrelated/unimportant details.
