We need entry level unskilled jobs matched to unskilled workers. That is a clear need. Most unskilled jobs can be automated, it's a simple fact. Some are more difficult than others. Maid services for example can be partly automated, and have been. I imagine most of the maids cleaning motel rooms are paid very little. We could end up with a rush to designing motel rooms that can be cleaned automatically. MIght be nice.
One Big Change coming "soon" is autonomous trucking which would eliminated millions of jobs were a guy can get a CDL and make decent money driving a truck. I think this changes by 2040. A lot of folks depend on truck drivers.
Uber/Lyft obviously will get to this also. We could have cities, portions thereof, where only autonomous vehicles are allowed.
