I wonder how this scales to a level of a city. Large cities tend to have larger innovation, which is partially attributed to the ease at which ideas can move between companies through job changes, serendipitious encounters, and a build-up of local business infrastructure. Would these sorts of agglomerative effects still occur in cities, if remote work is the norm and people don't have to be so concentrated? Or might these effects be amplified at the national level, because people can communicate more freely? I'm interested to see how this plays out over the next years.
