I mean some jobs requiere more or less training. No one is a competent product manager at 22, so of course that girl is going through orientation and training and not doing 8 hours on her first day.
My senior PM, who has experience in several big companies, and was well aware of our team stll took a couple weeks to get up to speed with how everything worked etc.
I don't think her onboarding day counts to call Google an adult day care. And seeing things like free lunch and a treadmill desks are just tools companies like google use to keep you longer in the office and maximise your time not things to take care of you. Its more work, but mango flavoured.
Work is work, but the same way we think of weekends as normal, or 8 hours as a normal amount of time we could think about 4 days, or having a gym next to our work as work. Being sad at work isn't a feature in my opinion
