Work is and always will exist....the robotics age has cut into the tedious, mundane, and dangerous work, but there is still plenty to go around.
The grass still grows, the leaves still fall, as does snow. Somebody has to deal with that, and it won't be a robot. Just because the technology
exists to do something doesn't mean it is economically feasible.
Robots haven't cut into farming much either. And construction, perhaps, if you want a community of boring ticky tacky houses that all look the same.
Every technical breakthrough has created jobs while killing off others. THe new jobs usually require more education for the few needed.
I used to be an electronics repair man, started in 1965....the job still exists, but only a small fraction of repair personnel are needed compared to 1965.
If you want job security, learn robotics, and even then, watch for changes within that might require you to retrain....
