I went from a Creality printer to a Prusa Mk4s on the last black friday sale. What sold me was that as they make new machines, you can just buy a kit to upgrade to the next version, instead of needing to buy a whole new printer. They’re also based in the EU, so even if they wanted to, they couldn’t do anything too bad in regards to privacy.
Doesn’t matter tho, cause I won’t turn on the cloud printing stuff, since I don’t see any benefit. Everything can be done exactly the same way without requiring external services.
I’m not sure where these numbers are from, but my guess is that you mean the Observable Universe, which is just the part of the universe that we can see.
We don’t know how big the full universe is, it could be infinite with an infinite number of stars.
