This video takes a look at the projected covid-19 death rate produced by models compared to the actual numbers seen around the world.

The Imperial model developed by Neil Ferguson originally predicted 500K deaths in the UK, was then reduced to 20K, and then again to 5700.

Ferguson wouldn't let people review his C code, which was written 13 years ago. Then said that Microsoft and GitHub were working on it.
