I remember this being common business practice for written communication (email, design documents) circa 20 years ago, so that people at least read the important points, or can quickly pick them out again later.
Possibly the dumbest, blandest, most annoying kind of cultural transference imaginable. We dreamed of creating machines in our image, and now we're shaping ourselves in the image of our machines. Ugh.
I think we’ve always shaped ourselves based what we’re capable of building. Think of how infrastructure such as buildings and roadways shape our lives within them. What I do agree with you, is how LLMs are shaping our mental thought how we are offloading a lot of our mental capacities with blind trust in the LLM output.
