A scientist has successfully encouraged mice stem cells to become a primitive sperm cell. Tests haven't been completed to see if these cells can successfully fertilize an egg.
I see no reason to assume that scientists and technologists won't be able to produce everything necessary to create a human being that haven't "real" parents. Genetically engineered, artificially inseminated, incubated in a tank and raised by a computer.
Lets create a new Adam and Eve to replace us, shall we? I wonder if that's what happened to the old gods?
Love.
