Well it isn't that we wouldn't want to participate but the EU is connecting our Horizon participation with other topics that have nothing to do with it. So I don't really see us rejoining it anytime soon.
As a small country, Switzerland will not be able to finance its world-class scientific infrastructure independently. It is a catastrophe. International cooperation is crucial in science.
Switzerland is a pretty rich country, and spends roughly 22bn CHF per year on R&D (about half that of France with around 1/8th of the population). Swiss universities are also a _lot_ better than their continetal European counterparts.
Wrong. We paid as much as we got from the program. The collaboration between scientist from across Europe was the more important thing. Sadly science got politicized.
