Re: Isnt that good?
As with everything, there's a trade-off.
Certainly on the environmental level, it's a clear win: less travelling, less pollution. There's even some secondary benefits at the city level: fewer traffic jams and less wear and tear on central infrastructure.
And at an individual level, if you're not travelling to work, then you're saving time and (unless you walk to work every day) money. And again, if you commute in a car, then you're putting less wear and tear on it.
But at the same time...
If fewer people are travelling, then that has an impact on public transport infrastructure - e.g. fewer buses and/or trains will run. And that not only means job losses, but has a disproportionate effect on lower-income people who don't have access to private transport.
If fewer people are working in a central office, then that means there's less demand for secondary industries to support them - e.g. sandwich shops, caterers, etc.
And similarly, if fewer people are in the city centre when they finish working for the day, then they're much less likely to want to go out for drinks or meals. So there's a further hit to the hospitality industry.
And both of the above support secondary industries - e.g. the people who grow the produce they server, and the people who deliver it.
Not to mention the secondary office industries, such as cleaning and security staff.
There's also the mental-health costs - social media and video conferencing only go so far as substitutes for in-person conversations, and there's fewer opportunities to meet new people. I know a few people who are worried about the toll that isolation is having on both their mental health and their ability to interact with other people.
And we're in the UK, which the dubious claim of having the smallest homes in Europe[*]. Which makes it even harder to have a dedicated workspare, especially if you have a family. Which in turn impacts mental health.
And then there's the cost of working from home - e.g. heating. I know it's offset for some people by the reduction in commuting costs, and some companies are happy to pay something towards your costs - and you can claim some money back from the IRS relatively easily.
So, yeah. Great for the environment. Great for the companies, who can cut down their cost base.
Otherwise, not so much.
Still, at least some of the above will have relatively short-term impact, and we'll learn to adjust and move to new economic models in the same way as buggy-whip makers did. But there's going to be a lot of pain for a lot of people along the way.
Then too, it's even possible that this could lead to something of a rennaisance for cities: with buildings being released from commercial and/or "student accommodation", we could actually see properties being refurbished and turned into housing, which would then get people moving back into central areas and thereby revitalising at least some of the hospitality industry which has just been decimated.
But I'm not holding my breath on that one!
[***] Personal bug-bear; around these 'ere parts, I'm fairly sure there's more "student" accommodation than non-student, thanks to the fact that they're not classed as housing and can therefore be built cheaply...
