I don’t know why people wish for money rather than immortality. Compounding interests baby!
Immortality has its own set of complications. Like seeing everyone you love die. Out living the earth, solar system. Being stuck for eternity in the heat death of the universe. I mean, I guess a longer life but not immortal might be desirable. Personally, my only wish would be to live comfortably.
There are far too many ways for an immortality wish to make your life hell in ways that a money wish uh, wishes it could.
