yep on the face of it (all politicians actually care about as everything they do is short term based) research in to certain things can appear to be pointless ,theoretical physics is a classic example. But think of the things that research in to this has lead to, it just takes time!
Lets face it the whole Brexit shit storm is BAD for science what ever way you look at it. I've said it before and I'll say it again the UK is BOTTOM of the G7 for funding science. And as long as we have so many clueless PPE fuckwits in government this won't change!
