> I once read a tongue-in-cheek description of San Francisco as “an assisted-living community for tech workers in their thirties”. This snide jab pokes fun at the wave of Silicon Valley startups creating services and products for a stereotypical technology worker in the city. Nowhere to park your car? Uber and Lyft can get you around. Too busy working to cook and do grocery shopping? Postmates can deliver your lunch and dinner. Living in an apartment too small for a laundry room? Rinse can do your washing.
