Maybe it's not wise to comment on this while living in Germany and never having been to SF.
But my first thought was: Are they gonna shuttle the kids in and out of the city in order to provide said childcare? Or the staff? How would the staff afford housing in SF on a "normal" salary? Where would they build the required buildings when land costs an arm and a leg?
The staff in my baby’s London nursery all live outside of London.
Edit: or are very young and live with their parents.

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.
