It is about purchasing power. Robots/AI don't buy food, don't travel (vacation at least), they don't need to buy anything. And the problem as I see it, is that it is going to happen in all areas at the same time. Because there is an insane focus on these things at the moment which we haven't seen before. Robots have always looked clunky and kind of useless so no one bothered with them, it was something of science fiction for most people I think. But given how many huge companies are actively working on it now, it means that the technology is going to come much faster.
This is Elon Musk:
Billionaire Elon Musk took to social media to express his agreement with a fellow tech leader’s prediction that there will be about 1 billion humanoid robots on Earth in two decades.
The Tesla Optimus, also known as Tesla Bot, was first announced at the company’s AI Day even in August 2021 when Musk said the company planned to build a prototype by the following year. He said of the robot at the time, "I think it has the potential to be more significant than the vehicle business over time."
"There’s still a lot of work to be done to refine Optimus," Musk said at the time. "I think Optimus is going to be incredible in five or 10 years."
As of 2022, Musk said he hoped to bring the robot to market in three to five years and that once ready it will be "an extremely capable" machine.
The intention with a lot of these robots is to serve as personal assistants for humans and also do whatever is needed at companies, and the estimated cost is around 20000$, so it is nothing for a company compared to hiring a person that needs a salary, vacation, etc. if it can do what is needed.
This is from Amazon website:
In 2022, 1 billion packages, or one-eighth of all the orders we delivered to customers worldwide, was sorted by Robin, one of Amazon’s robotic handling systems. We’ve become the world’s largest manufacturer of industrial robots and have deployed more than 750,000 mobile robots across our worldwide operations. It’s hard to believe how far we’ve come since the days of testing a few robots in a corner of one of our facilities.
From a business point of view, it makes sense, that if they can make a nearly fully automated system, they can save a lot of money. And just as with UPS, these companies are not unique in their approach this is where things are heading, it is simply the next "industrial" revolution we are looking at. Except before it was in certain limited areas which still required human interaction.
But it doesn't require a whole lot, when you have an AI more capable than any human in a humanoid body, to figure out who is going to be chosen.
You won't get rid of all humans at least not yet, but you don't need that either to create a catastrophe where politicians/we have to act. We all know how slow these political systems are and how inefficient this process is, so a few decades might not be enough. If his predictions are correct (he has been wrong many times before), then in the next few years we are going to see more and better robots getting developed, and a lot of these are not specialized in a certain task, but to solve many tasks.
And to me, this is going to happen the only question is how long it will take, these huge companies are not just playing around with billions of dollars just for fun, so we have to be prepared for the transition into a world where humans might be the worse employee you can hire.
