The industrial revolution increased the pace, but it was already there, not flat or randomly flunctuating (think ancient hominids versus early agriculture vs bronge age, vs ancient Babylon and Assyrian empires, vs later Greece, and Persia, later Rome, later Renaissance and so on).
Post 1970s most of the further increase has been based on mirages due to financialization, and doesn't reflect actual improvement.
Of course it does. It would be good if you would try to actually support such controversial claims with data.
