The link was to a Tesla video released just a couple days ago demonstrating just what is coming down the pike in terms of what a "robot" can probably do in terms of degrees of freedom of joint mobility, balance, and speed. So what are you saying? You didn't look at that because "my mind is made up?"
The idea that robots can't TOTALLY displace all physical workers within 5-10 years is, imo, absolutely established as plausible by that video alone.
What the video doesn't show, much less prove, is that the robots have (will have) sufficient tactile sensitivity to do something requiring a light touch. It also doesn't demonstrate "intelligence" at even a trained parrot level.
However, having interacted with certain LLMs for language learning, I am inclined to believe the robots will have no fundamental problem with being able to reliably match or exceed the skill level of skilled mechanics and construction workers within a handful of years. Which,if/when it comes to fruition, will mean that 99%+ of humanity has approxmiately NOTHING to do that the robots can't do better at probably vastly lower cost.
If so, humanity has an existential problem coming up quite soon. Hopefully humanity will rise to the challenge and start evolving upwards, but that remains to be seen, and the interim could be pretty depressing for the majority.
P.S. The video also makes a good argument for Tesla stock, imo, as the Tesla robots look, to my eye, to outclass the ones China has been showing off. And Musk only started on developing robots less than five years ago?
