Main thesis seems to be “millions of people have to leave where they grew up to find even halfway dependable work;“
Ok, the entire premise of the “digital nomad” is that work can be done from anywhere. The exact opposite of what is being argued here - if the work can be done from anywhere, then you can compete for that work from the comfort of your familiar settings. Or if you so choose, from anywhere in the world. That’s digital nomadism, not herding people into ever smaller spaces to make things more efficient.
A huge part of today’s digital work can be done from any well equipped home office or even a bench with a good internet connection and a power supply reserve. The fact that we MAKE remote work difficult is our own doing (me included) and will require a culture change that is well on its’ way.
