As someone that works in robotics/automation, it pains me to see people in creative/office verticals getting all the shit with AI these days while hard labor positions, the one that everyone could be doing a bit less because they take a toll on you (working the fields, farms, hazardous tasks) remain pretty much the same.
If you use a computer to do something, training an AI to use the computer to do the same thing just takes the computer, which was there anyway. (Yeah, plus training the model, that's not my point.) But if you do something physical, replacing you takes something physical to be there.
We may eventually manufacture the robots to do all these things. We aren't there yet.
I looked into this (or rather, had Google Deep Research do a 30-page report on it!) and it's still a very long way off. So long, that the AI, or any reference it found, would not even give me a rough timeline, but I suspect it is multiple decades away. The main blocker is a very severe crunch in the supply chain of critical materials, mostly rare earth elements which are essential to make those high power density + high precision motors feasibly.
Today we have a tiny fraction (like 2%?) of the global supply needed to make enough robots to replace all humans.
This is before we get to the other logistics like power and the rest of the materials, but we have a path to scale those up (except maybe Copper, that's another tough one.) Turns out rare earth elements are actually very abundant, but extremely hard to mine, very toxic to extract (which is partially why China has a strangehold on those) and we don't have a good path to scale those up.
All of this could be moot if we figure out alternative technologies for equally capable motors that could be manufactured at scale, but AFAIK whatever promising is on the horizon would still take a very long time to ramp up.
First, you make a robot that mines rare earth metals. Then construction robots. Then an automated factory for assembling robots. The whole premise is that the robots are faster at these tasks than humans would be.
If the robotics are feasible their rise should be exponential, not linear, since each robot built makes building the next faster and helps to remove whatever bottleneck you had.
> If the robotics are feasible their rise should be exponential, not linear
That totally does not follow. Robots can be feasible and their payback curve can still be linear or sublinear.
Take mining rare earth metals, for instance. The problem with mining rare earths isn't that it takes so much human labor. The problem is doing it without poisoning the surrounding 30 square miles. Replacing the driver of the earth mover with a robot doesn't fix the chemistry at all, nor (I suspect) does it significantly affect the economics.

There’s no quick answers, but intuitively I think we all get that the % of jobs not doable by AI and robotics approaches 0 over time.
