I thought this was slightly funny.
Mark Zuckerberg is known these days for wearing t-shirts with Latin phrases on them, especially ones where he compares himself to Julius Caesar.
Bluesky made a shirt in the same style, but theirs says “a world without Caesars” in Latin.
My understanding is that running most of BlueSky is possible on small to moderate hardware. However, running all of BlueSky requires basically cloning 100% of all the content on BlueSky (which, as of Nov 2024, was ~5 TB).
So, like, yes, one can run part of BlueSky or a clone of BlueSky which has none of the main instance’s user’s content without much trouble, but actually running an entire BlueSky stack is eventually going to become cost prohibitive.
I found this write-up to be enlightening on the subject.
