I’m not so sure about that. My outlandish prediction for what’s next: We no longer bother fixing household issues - if something goes wrong with the plumbing, we just throw away the whole house and 3D print a new one.
I label it an “outlandish prediction” because that’s exactly what people said about AI taking creative jobs — based on the technology at the time it was totally impossible, and then one technological breakthrough later, it’s an everyday occurence :P
The original point was that becoming a plumber is a good way to ensure you won’t be made redundant by the march of technology. My belief is that “the trades are a pretty secure job” is true today in the same way that “being an $80/hr writer is a pretty secure job" was true yesterday.
There are differences between those situations (eg the trades being physical, hammer and nail, custom jobs), but those don't seem like particularly impassable obstacles to me, given that technology has already made redundant whole categories of physical, hammer and nail, custom jobs.
