Harari isn't a 'futurist', he is using content he doesn't understand, computer programming and AI, and invoking a very OLD philosophical view of humanity, as it always is presented in a 'new' form, same logic, which Rationalism has always exposed in the past every time.

"Instead of producing cars and vehicles, the product 'this time' will be human bodies and minds."

The logic here depends on a flawed 'economic waves' historicism from Marx (hand mill to steam mill, etc), already refuted, and it also depends on an axiom of a divided humanity into two, bodies with one logic and minds with another logic, separate conceptual realities, which is just another form of the old dialectic from Plotinus, also already refuted.

"If humans interface with machines, we will not be able to know what will happen because our imagination is 'imited to organic, whereas inorganic is everywhere"

This is just the same Hegelian logic of megalomaniacal arrogant mindsets viewing physical reality as a 'fetter' against the drive to infinite aggrandizement, where the 'solution' to the supposed 'oppression' of subject sensing it is not all objects, to become the object, and for the object to become the subject.

This was also refuted as self contradictory and a projection of the same split logics dialectic seeking unity through absolute destruction of every 'thing'.

Harari isn't presenting anything 'new' other than what the old logic always requires, new willing dupes in the 'old guard' game of power and hierarchy.
