>But for about one-fifth of the economy, we get 5% per year productivity growth: a quintupling of productivity over a generation.<

How does one measure productivity in the knowledge industries? Does making an Excel worksheet dance increase productivity? What about quality? Are spreadsheets and presentation software just productivity sinks? How is quality assessed - because I don't see how hedonic adjustment can be used here. Does AI increase productivity, or just decrease quality with "AI slop"?

China certainly cranks out products at low prices. But the quality just sucks. Or compare desktop computer boxes made in the 1980s/early 1990s with the low quality today, because computers are commodities and tossed quickly? I recall that cars were value adjusted for quality. But if you look at cheaply made consumer goods today, their short lifetimes, etc., the quality has declined. [As has teh quality of stainless steel, where cheaper, less rust-resistant steels are now used, especially if sourced in China, where user comments often indicate rapid rusting of "stainless steel" items. Wall Street is full of knowledge workers, yet I don't see improvements in portfolio returns, so what is the productivity happening in that industry - managing more portfolios badly?

Interestingly, the homework assignments are more like real world tasks theses days. The exams measure the wrong thing.
