I think you're not really hearing my point. I'm not speaking about evaluating things just on the aspect of eliminating jobs.
I am saying that I would hate to automate away most joy or most things people find purposeful, even if it increases purpose or joy for some people.
We've already given up a lot of our social fabric recently with tech. I think it makes sense to be conscious and careful to not make it much worse.
It's my guess that delivery bots are a net add to well being.
But you are also not understanding my point. What automation or tech will end up useful and a "noble" use later on is never immediately obvious, it depends on a web of past developments which by themselves seem to have no connection.
