So should we all be farming and collecting berries? Most advancements since have put people out of jobs in "competitors" that didn't adapt. Still the unemployment rate isn't 99.9%. Yet we displaced whole industries many times over the centuries. Obviously people move to better jobs and find other things to do. There's nothing particularly good about sitting on a computer denying people insurance all day, why not have a computer do it?
If it is a choice between progress unfettered by concern for your "competitor's labor" or farming berries, I choose berries.
However, I believe there's a middle ground and endeavor to find it. Based on your response it doesn't appear as though you believe a middle ground exists.
Choosing berries (ie not progressing to "protect jobs" - no jobs are protected, we have close to full employment worldwide) is choosing avoidable deaths. Child mortality rate in a "choose berries" world is just one example that makes me triggered by those that have that position.
And you get nothing in return for protecting those jobs, as I said, the world is "employed" and we've killed many industries already over the centuries. You're protecting nothing.
