The money quote is the last paragraph.
The money quote you refer to, for those who can’t or don’t want to look:
“Drones are flying around Chengdu, reminding the people to stay inside and obey. This is an example of what could happen when government has complete power over the people. It can also affect the global economy, as we saw when Shenzhen entered a lockdown, closed the ports, and prolonged the supply chain crisis. Government’s abuse of power is yet another reason why it is hard for the central banks to forecast economic recovery. According to our computers, the recovery will be a slow process.”
