Well we won’t know what it’s long term effects are for the next 70 years... hell we’re even now figuring out that Herpes virus might have something to do with dementia...
And say we get a vaccine next year. Don’t you worry that if we relax lockdowns, we’re just gonna trigger the next devastating virus?
Let’s face it, life is a risk, and we accept a certain amount of elevated risk in exchange for comfort/utility (e.g. unprotected sex, industry-produced food, driving). This virus seems in line (at least for young adults). So the only real risk here, is government repression.
