It's not just the em-dash—it's the style of writing. The short paragraphs. The Consistent Titled Sections. Classic LLMese at its finest.

LLMs being based on probabilities and these are based on averages, hence whatever the LLM produces must be an average of what its been trained on.

So doesn't the LLM just regurgitating the average writing style of the internet and isn't the author just an average writer and hence the em-dashes.

The average is not necessarily a highly populated bin. It may in fact be empty (bimodal distributions can have this).

And the clanker doesn't even explain what changes for compatibility changes that Commodore and Bell agreed to and Bell didn't deliver...

Such a horrible piece of writing.
