Hi David

I loved that the police procedural was mentioned in the same breath as the gothic cathedral, as evidence of humankind’s dizzying future achievements.

I think you might have an interesting time arguing with evolutionary anthropologists about brain size being an unused bank deposit fulfilling its purpose only later in history. I would expect all evolutionary change to be paid for in the coin of reproductive fitness. If our savannah ancestors had big brains then they were always busy using them to the full and to their evolutionary advantage

None of which detracts from your delightful speculation.

Great stuff.

Joe
