I like this comment on the reddit thread -
"I also think we're really unlucky to have a government currently that is full of wack job sociopath types who believe in social darwinism and dodgy unproven behavioural science stuff, which has only been proven to work on nudging very targeted personality profiles through social media to vote a certain way, but really has not at all been tested on how to respond to a pandemic. But they are very narcissistic people and think they're cleverer than they actually are. They also aren't plagued by having a conscience or worrying about the fact people will suffer or die, so to them (i.e. people like Cummings) it's just an interesting opportunity to experiment and if people die well that's just another opportunity to smash some system or institution or another and build it back up as they see fit.
I think they are just way in over their heads but they don't even realise it. They are very simple minded people, who can have clever ideas in narrow domains that might work by fluke once or twice and so think they understand a whole scientific field from reading one or two popular science books about it for the layman, but are completely dense when it comes to any depth of understanding of the complexity of all these things and things like unintended consequences."
