The average guy or gal on the street across much of the US has never heard of Taskrabbit and many have never heard of Uber. And, frankly, that's a pretty dystopian future you describe. Fortunately, it's not here for most people. And if I drive or walk in a large city and try to imagine an AI navigating that chaos from door to door, my mind boggles. Not to take away from the impressive work that has taken place over the last five to ten years but the "replace human 100%" use case seems really really challenging--and far out.
