The app boom was similarly heartbreaking, only this time most tech workers didn't even need to explore the neighborhoods they lived in -- they could Uber to the front door of any restaurant they wanted, and take tech buses instead of riding their bikes or taking public transportation to get to work.
A few years ago I read that the average tenure of a business on Valencia was less than 18 months, which is nothing short of a death sentence for a neighborhood like the Mission. Long times residents no long feel connected to (or were able to take pride in) their neighborhood, and most new residents don't care to to establish those connections -- why bother if the upscale boutique that replaced a multigenerationally owned family business is just going to be gone in a year an a half?
I mourn what happened to the city I used to love, but I'm optimistic that the decentralization of tech will leave San Francisco a better place.
