It was about the same price to hire a nanny as it was to send 2 kids to daycare, so we did some interviews and hired one.
That 2 years was probably the easiest stretch of dual working parent life that we ever had. She did a load of laundry and a load of dishes each day while the kids were having naps. If we were low on detergent or supplies that the kids needed, we gave her cash and she'd pick it up on her way in. If somebody needed to be at the house for some reason, she was there and neither my wife nor I had to remove ourselves from work to take care of it.
We literally came home from work, ate dinner, played with the kids. When the weekends came around we didn't have to dedicate a chunk of it to laundry/cleaning.
It was pretty fantastic.
I can only imagine how having a actual assistant would take things to the next level.
All that said, the types of phone calls that Google is talking about making here aren't that beneficial...yet.
When Google can call my cable company, wade through the phone tree and get a service appointment or issue resolved...I'll be all over it. Even just wading through the phone tree and sitting on hold until an actual person is reached and then handing it back off to me.
Those are the time wasters I'd want saved. What Google is doing here is equivalent of automating the functionality that people pay for with OnStar.
