"Superalignment" is (was?) OpenAI's term, so it might be more accurate to say he is joining Anthropic to work on alignment.
they worry about alignment for ai, I worry about alignment for the corporations that wield technology, any technology.
It seems to me that the only way to achieve superalignment is to not create superintelligence, if that is even within our control.
Note that misalignment between these systems is very common.
Their purpose is to control the population by being lesser beings who feed off corporations and just push their message.
