So what? Over the course of the next year the students will be in many situations where they sit next to other students. There's nothing special about a lecture theatre, it's just a room. The reaction by Cambridge here is bizarre and seems ungrounded in any kind of logic or common sense. 2021 is far longer than any other kind of lockdown measure is proposed for, far longer than epidemics usually last, students are at no risk and the older people around students can't simply avoid all contact with young people indefinitely. Cambridge students should just ask for their money back and/or not sign up to begin with.
