> It's a singular failure of Silicon Valley that so many tech jobs still need to be done in person. Even if they could be done remotely, people still want to live in cities for lots of good reasons - reasons that are centuries old. Today, a large number of people who live in cities work without a common central office. This goes beyond tech workers to include lawyers, accountants, designers, in-home businesses like child care, and trades conducted strictly at client sites like landscapers and handymen. The density of cities supports those sorts of work arrangements, and other things that a significant number of people value, like museums, libraries, parks, etc. As a social technology, cities have demonstrated a tremendous amount of value per unit of investment, which makes them a natural target for investment.
