I think it'll be a catalyst for massive societal change. Fair enough, if a vaccine appeared this Summer and everyone could get back to "normal" in the Autumn, things may not change too much, but realistically that's not going to happen and we're going to be in a state of limbo for a year or so, if not longer.
So many people will lose their jobs, professions, livelihoods, businesses - they cannot be furloughed/supported for a year or more. Sooner or later the crunch will come and redundancies/closures will have to happen.
Even if flights/airports are able to reopen for anything close to normal services, I think huge numbers of people will be put off flying, not only due to the risk of catching something, but also due to the almost inevitable worsening of the already pretty appalling experiences of delays, security checks, cramped conditions, and potential extra health checks.
People have grown accustomed to the current way of life - not partying/clubbing, not having their hair/nails done, not going for coffee/cake every morning, etc - it's all habitual and lots of people will have realised they don't need it so often.
Firms will have staff working from home - realising that can continue. Managers may have seen which staff are productive and which aren't.
People may never go back to using public transport so much.
The longer this goes on, the less likelihood we'll go back to anywhere near the old normal.
