It looks like a silverfish to me, but I've never seen them bigger than about 1cm.
https://en.wikipedia.org/wiki/Silverfish
If I’m reading this correctly, they shouldn’t be harmful to humans, right?
I’m wondering whether I should report them to someone or let them be
They don't hurt humans or pets. They'll also tend to hide, given the opportunity.
They do like to eat paper, however. One silverfish isn't a big deal, but if you see them often it's worth looking into deterrents or pest treatment. When there are lots, you'll start to notice holes in notes, books, etc — most particularly (in my experience), loose pieces of paper left undisturbed for a length of time.
I've had a few in my apartment. I sprinkled dichotomous Earth where I saw them and haven't seen any more for a while.
Sounds like a cool book title or band name.
I think autocorrect screwed you and you meant diatomaceous?
But not both!
Inclusive or
Ha, a dichotomy is XOR by definition.
Jointly exhaustive then
Maybe it's just a very tasty book and they haven't come back because they're so full.
Correct!
