That's just not true at all.
Plumbers and electricians and carpenters are not going anywhere. A residential plumber will not have their job automated this or next decade, at best they'll have some fancier tools to play with.
Things happen not at all and then all at once.
We have the cheap humanoid platforms coming out of China and they cost six months minimum wage salary in the developed world. Once a model is developed that can use those platforms to match humans for simple tasks we will see the hollowing out of all unskilled physical labor overnight.
What I'm talking about is that I use Claude daily to find stupid bugs in my code. I can now spend my time on things that matter.
This was science fiction 5 years ago.
A person knowing how some brick houses in Y neighborhood tended to be built back in 1890 won't be replicated by prefab anything.
Of course you’d still need training on how to work with your hands but it would cut down on the need for years of experience and planning.
I wouldn't be so sure about that.
Power systems have a long way to go in terms of integration with data. One can envisage an inherently safe system whereby a data signal is superimposed on the wire (related to data-over-power) and every power source continually interrogates its loads and conditions on the wire are being continually monitored. Any unsafe situation will result in a shutdown of supply.
I'm describing a system that goes well beyond existing breakers and earth leakage: one that is able to fully map the connections between components, know the topology of the system and compare actual and expected behaviour. The idea is that any dummy could do electrical wiring, as the system itself would make it impossible to create an unsafe situation.
Cost would be higher to start with, but with economies of scale reducing the difference, my guess is that the higher cost of components could be offset by lower installation cost and the increased safety.
Electricians are not going anywhere, this decade or next. I stand by what I said.
