This novel I read rather recently, during the early "Covid" years. But I don't remember much.
One thing I am positive about is that, in this universe, one can upload the mind of people (usually, just when death is imminent) into a giant computer in which they keep "living". But contrary to the case of, for instance, John Varley's universe, one cannot download them back into clones in the "external" world. They can only continue to "live" in the computer.
Only one specific episode remains in my memory. One of the main characters, a young woman, is given access (from the outside !) to the computer. (IIRC, at some point later in the book, she will die and end up in the computer). She is told to choose a long password that she can easily remember but that nobody can guess. So she took the acronym of a rather long sentence. I cannot quote it verbatim, but I am probably very close. Something like : I S(tole) A(n) A(dhesive) A(nti-slip) D(uck... Hmmm... an adhesive duck is mentioned the Big Bang Theory; here it was probably something else, maybe an adhesive flower) F(rom) T(he) B(athroom) O(f) M(r) W(hatever the name was)'s M(ansion). She can remember it because she actually did it, as a joke, or to keep a souvenir. But nobody saw her and could ever imagine she would choose such an acronym as password.
