Thanks for summarizing 3,400 words. The piece was so rambly.

I for one absolutely love self-checkout at groceries, self-checkin at airports, etc. The parallel processing benefit is obvious, and ignorance is bliss when it comes to operator errors. And the more such self-service procedures become mainstream, the better we as a species become in reducing those errors. As a frustrated Android user in 2010, I used to think the general population wouldn't be able to figure out smartphones. Boy was I wrong.
