I do fancy living in the countryside, yes. But although I love doing that for a weekend (we just had a weekend in Somerset, staying at a pub with great food, great walks etc.) I fear I might get bored with the limitations. I love the fact that within a 3-4min walk I have about 5-6 pubs, 3-4 independent coffee shops, a local grocers, a butchers, a few restaurants and that's not even including if I walk 10-15mins into town 'proper'. Like everyone, it's all about balance...
Personally I think that humans are a social species and we'll never get away from that. Therefore cities will always thrive, people will always want to work with others in person.
Both mine and my girlfriend's company's have said they're expecting to WFH until the new year. We don't really have many friends this side of London, and we have no car. So really we only have ourselves for company which is a scary though for another 4-5 months! I don't fancy only speaking to her and the neighbours indefinitely!
