I'm somewhat skeptical of this "enter the trades" movement. Actually, I am more skeptical of that statement than I am of LLM's replacing white collar work in general. I think parts of coding are being replaced quickly because they are the parts that don't require discernment. Trades likely contain just as many automatable and just as many discernment parts as white collar work. At this moment in history, the automatable parts are being automated in the knowledge based world. People think the physical world is somehow different, but with world models (along the full spectrum of what that means) the physical world will be just as trainable as the knowledge based world.

tldr; Just like knowledge work, most trade stuff is probably mostly repeated (i.e. very trainable) task with a small amount of taste and discernment applied. The repeated will be trainable, the discernment may be trainable. I don't think the physical world is necessarily any safer than the knowledge world.

The difference is the physical aspect of the trades. The design for wiring can be (and already has been) automated, but you physically need an electrician on site to pull the wires. So I can see a hollowing out of the engineers, but not the actual electricians.

That being said, the absolute focus on trades from the fed right now just reeks of the wild pendulum swing. It used to be 'go to college to get a good job' then we had too many college grads. In ten years we'll have a glut of people trained in the trades with no prospects.

It just keeps swinging back and forth and somehow Joe Regularworker keeps losing.

Robots are expensive, software is not. I can instantly duplicate software 1 million times and run it in parallel, I can't just produce 1 million robots. Physical world is always harder.

Even if we get robots who can, say, build roads start to end, there is still a HUGE gap between that and it actually being used. There is a hard floor, too. Robots are made of physical things, physical things have scarcity, and there's no way around that to our knowledge. Even if you can build the robot for 1 cent, the material cost will still exist.

Hasn't the US already minimised the cost of all the construction work that are "the parts that don't require discernment" to minimum wage who-cares-if-they're-documented-or-not day workers?
