Cost prohibition is a preeeeeeetty big deal. And as long as biology exists, the economics will never get there. You're talking about replacing (skilled) human workers with cutting edge ultra advanced androids, which even then can't come close to matching the degrees of freedom of a human. Robots are made of metal parts, which are absolutely bulky, clunky, and massive compared to protein fibers.
It's absolute nonsense. Every person will have their own flying car before getting there. Automation will be limited to stationary structures for a long long time, and then only break out into mobile applications very slowly.
The experience you state is stationary automation, with countable degrees of freedom.
people said the same thing about machinery at the first wave of automation. "why would i spend 100k on a labelling machine, people cost 5$/hour". and now in america 99% of all products are labelled by an automated machine. cost is 1 part of the equation, mistakes are another. people make more mistakes than machines, and machines work faster. this greatly offsets the costs with productivity increases.
in context tho your whole "stationary structures" thing is largely nonsense. firstly because we're talking about manufacturing, where its all stationary anyways. and secondly because even in dynamic applications you can easily make robotics mobile, such as produce sorters which they just install behind a picker. the robot doesnt need to move, u just need to move the robot.
really tho the issue that everyone who thinks like you is they dont understand the basic math. you have a % of the population that works in manual labor, and a % that work in white collar jobs. automation is currently eating at both sides, and a lack of new jobs are being created to replace that %. its simple math, if automation takes more jobs than the market creates in new sectors then too many people are put out of work. and i know your response "well new stuff will be made, it just has to", but that's false. a higher % will be automated than is created, its that simple, and its inarguable. 100 years from now whether you like or accept it or not a large % of the population just wont work jobs, at all. they'll be apartment dwelling unproductive members of society who will likely take a few extra food vouchers to voluntarily sterilize themselves.
