The flip side of this is that it helps to speak in a way that’s almost repetitive to make sure someone who zoned out can catch back up.
For example, frequently once the subject/object of a sentence is known, people refer to the subject/object with pronouns instead of repeating the subject/object. If someone misses the initial definition, they are immediately lost.
(This also applies somewhat to writing — above, I’m repeating “subject/object” instead of “it”. People also zone out during reading, and this repetition saves them from having to scroll back up and figure out what a pronoun is referencing.)
As a counterpoint, Sydney showed aligning these models on the first go, and even discovering unsafe behavior is non-trivial.
