That's an odd reference to DEI. I'd say the negative consequences of authoritarian regimes is that they suppress freedom, and therefore art and technological innovation.

China is authoritarian, but also has a huge political system, somewhat strong institutions. That can't be said of many authoritarian regimes, which tend to be more fragile. It takes a really long time to build civil institutions. For example, Russia has the money and an authoritarian regime, but repeatedly fails to innovate, and we can't predict what will happen when Putin leaves.
