If only it were just the world of work...
I know it's human nature to try to be optimistic, but I am staggered that so many people don't seem to realise that things will never get back to how they were in 2019 because it's simply not possible.
The very environment that sustains our lives is extremely out of kilter, between unsustainable agricultural practices and deforestation, and speaking of agriculture, between a climate that is both changing and less stable than it used to be, the future of a lot (most) of traditional agriculture isn't looking terribly good. It isn't a case of simply needing to farm different areas instead, either, because the key factors that our food supply depends on are the stability of the climate, and the soil where agriculture is practiced, and collectivity, the majority of the worlds leaders are still doing very little of any effectiveness to try to tackle the things us humans have been doing that are adversely affecting the climate we're used to.
Then there's logistics. I doubt very much whether the supply chains that support the world that was, and which, for the moment is staggering along in an attempt to maintain "business as usual", will continue to work so well much longer. Between some logistics folk having to self-isolate and others becoming unable to work due to the pandemic, that's liable to be somewhat disrupted in the first place.
But with international movement of goods and people more restricted, and, in the case of foodstuffs, the source of supplies becoming very unreliable or even vanishing altogether due to changing and unstable climate... yeah. Good luck with the "reboot 2019" efforts, I shan't hold my breath waiting for anyone to succeed with that.
WFH or working locally rather than long commutes is a good step in the direction of reducing the amount of crap that's unnecessarily spewed into the atmosphere, and needs to be promoted as much as possible. As does manufacturing things to last and be as repairable by owners as much as possible, stuff that needs less energy to be made and less energy to run, everything recyclable, etc, etc.
Air travel and the holiday business will likely never be remotely the same again. When I was a young child, the expectation many now have of being able to go abroad for a mere holiday every year (let alone multiple times a year) wasn't anything other than a fantasy, except for the extremely wealthy. And the world population then was a little over three billion, a figure that was already beginning to worry some who could forsee the way things were going (which didn't include myself for another 20-30 years).
The thing about money is that it's a collectively agreed system for making exchange of goods easier, and has only the value we collectively choose to give it. At the moment, it's nice to be in a situation where a computer somewhere records ones bank balance as being a large positive integer. What happens to that money if the IT sustaining the banking system stops working? Exactly how much worth does that number in a computer somewhere have then?
Ironically, it's the "business as usual" brigade that are most likely to bring about the collapse of the civilisation we know and force us back to something resembling at best, a mutated form of Mediaeval times, and those trying to work on and implement genuinely "greener" ways of doing things that just might, if we're lucky (please, may it be so!), manage to keep some semblance of civilisation going.
If they succeed, the world won't look much like 2019. Goods made to last and be user-repairable, so less sales of"stuff" and less transport thereof. Localised production using 3D printing where necessary/possible to an increasing extent. Dietary change for many due to a shift towards more sustainable food production, including large amounts of "vertical farming" and "lab produced" products.. Less travel generally. With luck, heavy industry and mineral resource extraction starting to move out into space. Much greater use of geothermal power generation, as well as solar, and if anything, a little less hydro (due to its harmful effects on both ecology and climate); more and safer nuclear power (like hot salt thorium reactors).
If they/we don't succeed - well, I doubt very much whether anyone will be wondering about whether they'll be able to work from home - they'll be too busy just trying to survive.
And on that note - mine's the one with the little ray of sunshine in the pocket...
