alt Hacker News> Are they gonna shuttle the kids in and out of the city in order to provide said childcare?
The city itself is tiny, this is not the metropolitan area of San Francisco, its just the city limits, so yeah people in suburbs will commute into the city to work there, just like most other people working in San Francisco.
There's also great (by American standards) public transit into/through the city. Caltrain and BART can get you into SF quickly from quite a large area nearby.
