Physical labor, especially jobs requiring dexterity, will be left for a long time yet. Largely because robotics hardware production cannot scale to meet the demand anytime soon. Like, for many decades.
I actually asked Gemini Deep Research to generate a report about the feasibility of automation replacing all physical labor. The main blockers are primarily critical supply chain constraints (specifically Rare Earth Elements; now you know why those have been in the news recently) and CapEx in the quadrillions.

Didnt people say that AI is 50 years away in 2010s?
Yeah and until ChatGPT I thought even 50 years was optimistic, which is why current days feel like SciFi! However, at its essence, the current AI revolution has been driven primarily by a few key algorithmic breakthroughs (cf the Bitter Lesson), which are relatively easy to scale up through compute.
On the other hand, the constraints on robotics are largely supply chain-related. The current SOTA for dexterity in robots requires motors, which require powerful magnets, which require Rare Earth Elements, which are critically supply-constrained.
To be precise, the elements are actually abundant in the Earth's crust, just that extracting them is very expensive and extremely toxic to the environment, and so far only China has been willing to sacrifice its environment (and certain citizens' health), which is why it has cornered the market. Scaling that up to the required demand is a humongous logistical, political and regulatory hurdle (which, BTW, is why I suspect the current US adminstration is busy gutting environmental regulations.)
Now there may be a research prototype somewhere in some lab that is the "Attention Is All You Need" equivalent of actuators, but I'm personally not aware of anything with that kinda potential.
