I think some more progressive workplaces will have moved more permanently to home working, where possible - possibly with monthly face to face get togethers.
Schools that have coped well with bringing in online learning will be on standby to do it again at short notice and will be asked to help schools that have not.
There may be some realisation of how precious our NHS is and support for a ringfenced increase in taxation to support health and social care.
The landscape of the high street, shopping centres, the arts and leisure industry will have changed forever and be more sparse. Online retailing and streamed events will continue to evolve.
People will have spent money they would have on holidays and leisure on improving their home environment to make staying at home more a nicer experience.
If a vaccine hasn’t yet been developed, work will still be progressing steadily towards this.

Friendship groups will have been weakened based on who did follow the SD rules and who didn’t.
Those who have had to shield will continue a reclusive lifestyle and mental health will suffer significantly.
