The notion of superhumans is using bioengineering and artificial intelligence to upgrade human abilities. If they use the power to change themselves, to change their own minds, their own desires, then we have no idea what they will want to do.

Traditionally, life has been divided into two main parts: a period of learning followed by a period of working. Very soon, this traditional model will become utterly obsolete, and the only way for humans to stay in the game will be to keep learning throughout their lives and to reinvent themselves repeatedly.

I grew up in a small industrial suburb of Haifa in Israel. As far back as I remember, I was interested in big questions. Who are we? What are we doing here? But the chances to discuss philosophy were quite thin on the ground.

A duped newspaper or magazine could contend that a fiction-spouting journalist obtained part of his salary via fraud, and use a criminal proceeding to try and recoup that money.
