You don't have a counterfactual to suggest that it would have continued increasing had it not been for technology. Is there _any_ credible economist who suggests that we might have higher productivity without tech?
There is no counterfactual needed. Productivity growth has declined, despite the expectation that software would accelerate productivity. I'm asking you why this didn't happen.
I'm not even proposing that growth would have been higher without "technology". I said information technology has not increased productivity growth compared to the past. This is an observation of fact.
