For fucks sake, R289, R290 and R291 (and anyone who feels obliged to suggest their own specific city's metro system.) How do you you think people will get to work, to go to school, to the airport, to see a museum exhibit, to get a marriage license, to attend a court hearing?
You think that we should just digitize the content of museums, sell off the art works, and put it all online? That we will shut down the airports because videoconferencing and video-tourism and tele-teaching and tele-justice and home delivery will shut everything down? And we all just stay at home all the fucking time behind locked doors, a safe distance from any neighbors, never setting foot in the world?
It's not just people writing computer code on his laptop in their guest bedroom/office instead of an office cube in the city center, it's the people who make the laptops, the people who repair his toilet, the people who keep Netflix with a supply of films and series so we don't have to read, the people who live near fuck all who grow our food, the people who deliver all of these things,
The 19th Century, to take just one example, was a plague a minute: cholera, yellow fever, typhoid, scarlet fever, smallpox, more... Huge waves of disease with enormous death tolls followed by more and more, year and year, decade after decade. In retrospect people made a lot of hindsight-stupid mistakes, but the population would have declined to nothing had they all stayed in their houses for a century until things started to get a little better. Except it never really did, certainly not from1918-1922, and not with polio and smallpox and influenza and the rest.
In two centuries of rampant disease and death, great novels were written, art movements changed the way we see the world, jobs changed, ways of working changed, healthcare and longevity changed, travel and communications changed everything, some obscure places became big and important while others declined, new countries arose, and none of these things happened because people retreated from cities and closed lines of connection and stayed at home for years (magically, as if even plausible.)
