No - you're questioning all economies. The questions you ask could have been asked at the start of the last century. Again, think of the economy as things to be done and people to do it. As such, it really will never end.
We are increasingly looking at an economy that requires less people to do it,/ in case you haven't noticed. So yes, I do question that. We can't all work in an Amazon warehouse shipping things to each other, because that will become more automated as well.
I ask questions, you respond with faith. I don't know why because change isn't automatically positive.
