> Everything that could be done by a purpose specific robot arm bolted down to the factory floor is already done by a purpose specific robot arm bolted down to the factory floor.
Hah! Hardly. I say this as someone whose first "real job" was in applying robotics research to automotive assembly - there are still a ton of assembly tasks that could be performed by a fixed-base robot arm, or a robot arm on a linear rail/fixed gantry. Wheeled mobile manipulators are only needed in a few cases, and humanoid form-factor is only "necessary" in very few cases (and I don't think the current crop of humanoids is particularly suited to these tasks).
In my opinion/experience, the impediments are that (1) the system integrators that are usually responsible for assembly-line robotics are too stupid to figure out how to apply robots to the problem, (2) the automakers themselves are often too short-sighted/stupid/unwilling to invest in increased automation (and particularly in building the in-house competency that they really need), (3) the hostile/exploitative relationship between (most) automakers and their main suppliers means that low-hanging improvements to parts/assemblies are a non-starter, and (4) the automaker C-suite (and investors) are too drawn to silver-bullet solutions (e.g. humanoids) than practical automation improvements.
"Could be in principle" and "could be in practice, under technical and economical considerations in play" are two very, very different beasts.
Everyone in the industry learned that the hard way.
At a certain point, the tasks that remain stop being "dexterity" problems and start being "AI" problems. That is: a robot could do the task - if you either spent big $$$ on redesigning the entire task around the robot's intellectual limitations (uneconomical), or if you had an incredibly advanced AI capable of problem solving driving that robot (impossible with 00s AI).
The "universal robot" bet is the "incredibly advanced AI capable of problem solving" bet. That in 2020s, AI is finally capable. The body only has to be "good enough to make most tasks possible".

The auto industry is notorious for making incredibly myopic choices to save money/make money in the near term versus long-term investments. The relationship between automakers and their suppliers/vendors is basically a century-plus of the automakers trying to (1) outsource anything they can for a quick buck, and (2) grind the supplier/vendor margins down to nothing. (This is part of why the newer Chinese automakers with much greater vertical integration are such a threat to the traditional automakers; vertical integration has a high up-front investment but the payoff in flexibility and speed is significant).
How long ago was your robotics experience?
An Amazon warehouse or Tesla factory tour would likely change your mind.
I had to do both of these in the last year and not a lot of humans around…
I have visited factories for work and my experience is the same. There is so much stuff that could easily be automated but is not because it is too expansive for too little value to make a custom one off machine. The big high volume things will be automated but these machines will have 90% success rate and lot's of stuff that needs to be done by hand. You can search for factory tours on youtube to get an idea. Here are two videos, an Amazon warehouse and a Tesla factory. the big heavy stuff is automated but lot's of work is still done by hand. https://www.youtube.com/shorts/-R6cBkza17k https://www.youtube.com/watch?v=45slYC99uUg

This is over the last decade at one of the largest automakers in the world. Naturally there is significant variation between individual lines and plants; some are newer and more automated, some are older and much less automated. Are some cars being built on more automated lines? Yes. But a great many, probably the vast majority, are being built with fairly low assembly* automation.
* There is a significant split in automation between "body weld" stages and "assembly" stages. Body weld is very heavily automated basically everywhere (although there are some surprising exceptions in places), while assembly is much less automated.
“One of the largest automakers in the world” makes me think of very low-tech companies like Ford or whatever. I can’t imagine this would bring much actual experience with this new generation of robotics.
Ford doesn't even make the top 5 - and however "low-tech" you think these companies are is the point, the overwhelming majority of new cars are being built by those "low-tech" automakers. The problem is not the limits of current technology (or even of the state of the art 10 years ago), it is the lack of vision and will within these companies to invest in using it.
> I can’t imagine this would bring much actual experience with this new generation of robotics.
Luckily for you, my job has always been within the robotics research side of the company, so I am very much aware of the strengths and weaknesses of the current technology.
What an unnecessary comment dismissing the expertise of an actual expert - what’s your robotic experience to dismiss him so contemptuously?
automotive workers unions started around 1918 and became major political players in the 30s -- a fact that i'm sure is wholly unrelated to why there are so many un-automated tasks in that industry.
Hyundai’s manufacturing facilities in the U.S. are not unionized.
Amazon warehouses still have a huge number of ununionized workers doing manual labor
Pretty different tasks, environments, outcomes, metrics, goals, and other things in a warehouse vs. a factory… really have no clue how this is supposed to be relevant. Why not mention farms or libraries?
Also, a general purpose robot vs a custom purpose robot represent very different capital investment profile for the factories?
