That doesn't mean there aren't downsides, though.
Sure you could automate that kid, but while trying not to be sappy, that's another face you get to see during the day amidst a traditional day filled with computers, iPads, and now according to this -- machines making our food.
When I want to socialise with people, I'll go to a bar, my friend's house, a coffee shop, etc. If I want a burger, I want to get issued with that burger ASAP, without having to deal with someone who you may consider to be a nice person, but I may consider to be a douche-bag.
If that well-paid smiling person didn't have to work at the burger place, she might have something more interesting to talk about when we meet in a proper social environment.
Sometimes I can go a few days to a week where me and my friends are all busy doing things, I buy all my stuff from the self checkout or via amazon and don't really interact with anyone.
Then when on friday night I go out to a busy party it feels like a shock.
Don't get me wrong, I think some work certainly could be automated, but at the same time, we need to consider the human cost of automating that work. A glib response of "learn how to write specs" or referring to people that do some tasks as "fucking idiots" does very little to advance the conversation.
