We keep hearing that Hawking makes his concerning comments about subjects like AI, aliens and now national health insurance. He is a theoretical physicist.
Hawking is using his position of authority in physics to push for progressive political change. I'm not saying I'm against this but I'm of the view people should take a more realist approach to articles such as this.
BTW Jeremy Hunt's only qualification to be in charge of the NHS was to be the MD of Hot Courses before he became an MP. Who cares?
