There are subjects which naturally lend themselves to “shifts” inter-sentence. Not really technical matters if the technical matter is just a list of specifications: here is how this works by default and if this and that then this happens. More like subjects relating to social issues and philosophy.
A person may have no preconceived notions about what the frobricator does. So you just list it out. But they may have plenty of preconceived notions about some more abstract-but-relatable subject. The writer anticipates that. And they have to navigate this subject at many levels at the same time, either inter-sentence or inter-paragraph; now I am talking about X, but not the X you think [the writer anticipates] but the X in itself. And not the X that group A considers, nor the one that B considers...
These subjects are more common in the “humanities”.
Certainly some authors overdo it and just seem to produce sentences with multiple semicolons and em-dashes because it’s their style/they are showing off. They are not writing clearly.
(Here I am using """""smart quotes""""".[1] Why is no one arresting me for that?)
I think we have seen a rise in the use of more intricate prose among technologists concurrent with the rise of AI penmanship. There’s more “flavor” now. Less of, either, straightforward prose or just boring and stodgy prose. More supposed personality.
Whatever the cause, this could be an emergent property of authors competing for readership by writing on the same subject but in a more supposedly engaging and personal way. And if an author who doesn’t like writing prose but wants to promote something regardless could get help from a program which happens to be literate in English as well? Well. Now it is easier to ramp up the word count.
> > If your goal is to have other people read and enjoy your writing you should make an effort to edit your thoughts.
Now the sentence says something different. The original said: If your goal is to get people to read ... And hopefully also enjoy.
Just getting people to read has the primacy in the original.
> > If your goal is to have other people read and enjoy your writing, you should make an effort to edit your thoughts.
This is certainly how I expect a programmer to write.
> Again this is probably a cultural thing, maybe a reaction to AI as well, but I find the em-dash a lot more though-interrupting than the other punctuation choices and I wonder if it's something I'll get used to or not.
Some groups of people ponder the great questions of life.[2] Programmers ponder if there is really a categorical difference, in principle, between their own consciousness and that of their smart fridge. And whether em-dash users are bots.
It is a cultural difference.
