The cause of humanity's decline is left vague until the end, but it becomes obvious, as the valet robot goes from one job opportunity to the next, that humanity's destruction is self-inflicted.
The book flowed well and held my interest. I could see how humanity's dependence on technology could eventually result in our demise. The book is not uplifting but it was entertaining.
I gave the book four out of five stars on Goodreads. I enjoyed its portrayal of our bleak future.
