I think there will be massive changes to the economy and a significant recession to get over once the health crisis is resolved.
But in the longer term, I think there will be wholesale changes in society also. We will have less long distance travel - already the reduction in travel and economic activity is allowing Carbon emissions to drop and nature to emerge in places it had been existing on the fringes in recent years - clearer waters in Venitian canals, lots more birds singing in our area, reductions in smog in other cities...
We will become more aware of looking after ourselves and having sufficient buffers ready for emergencies. More like many of our parents and grandparents were after the World Wars and the shortages they had then (I don't think there will be shortages, just that people will understand that supply chains are more vulnerable than they look to shocks).
I hope there will be a return to more community values and less of the "me me me" culture that I have seen rising in recent years - people do seem to be pulling together at least at local levels.
And I hope that there will be a chance for society to slow down a little, and people to realise that you need time for everything and not having to get things done right this instant. Like the slow food movement had been trying to do for good food, but for life in general. It's not all about instant gratification.
But I think that there will also be a greater recognition of the value of some modern technologies like the internet and social media for keeping in touch. And that older people come to see that value too. That it's not all about stoking outrage on Twitter but sharing good ideas like fitness videos to do at home etc.
And hopefully also that employers will, generally, be more facilitative of people working from home (I know not all jobs are suitable, but many more are suitable than employers like to admit) -and realise that people can be trusted to be productive when WFH.
I also think that we are likely to see a change in how people eat, I don't know if veganism or vegetarianism will rise (although there will be some who use this to call for it), but I do think that we are likely to see an increase in using local and seasonal produce again rather than ingredients that are flown in from far away. And hopefully also a reduction in food waste as people learn to only buy what they need, and to buy for a few days at once not on a daily basis. Planning how to use what they have and making use of leftovers, etc.
I suspect that there will also be a significant shift in population pyramids, unfortunately, that there will have been a significant increase in deaths, and particularly amongst the elderly, worldwide. There may well be a huge spike in births in 8-12 months time also.
But there may also be a change in how people live - reducing densities in cities, and putting in better infrastructure to allow WFH etc in more rural areas which will allow those areas to develop more. Spreading out the population somewhat.
