In the near term, only unskilled labor is really at risk. Even so, plumbing has no potential for growth in developed countries above the rate of population growth. It's something you only care about when it's broken. The key to avoiding huge disruptions in the face of advancing technology is having new jobs for displaced workers. I don't see it.
There are plenty of jobs that will be automated in the next decade. What will those workers do?
" It's something you only care about when it's broken." - you do realize that plumbers are needed for new construction and renovation? Actually, given the needed improvements in infrastructure and new building projects, a lot of skilled labor is needed. I am really not seeing robot electricians, plumbers, etc. for many decades to come.
I am really unclear what you think unskilled labor is.
I really don't think the labor stats match your belief in regard to the skilled labor, and I the unskilled positions your are mentioning are being limited more by raises in minimum wage / economic conditions versus automation / demand.
