"Descartes made an exception for the human soul, which is not a part of the material world, and therefore is not governed by laws of nature. The immaterial soul accounts for man’s free will.

However, most advocates of AGI (and advocates of strong AI) will today exclude Descartes’ immaterial soul, and follow the arguments of Yuval Harari."

What are we doing here? If we bring "immaterial soul" to the argument as a requirement than the author is right, AGI is unrealizable.

ps. I flagged the article, not up to HN's standard IMHO.
