I don't think that the author got it all exactly right, but your points are wrong. Business is driven mindlessly by ONE THING--maximizing profitability. The time will come...and right soon...when machines will work well enough to eliminate many existing blue collar jobs and a large fraction of low-skilled white collar jobs too. There is and will be pushback, in the form of higher minimum wages and requirements for health insurances. And all those pushbacks do is accelerate the process. We can likely thank China, India, and Mexico for providing cheap labor and forestalling the onset of this mechanization a decade or two. Had they not been there to take our manufacturing jobs, serious automation efforts would have started even in the early 90s. As greed is the only acceptable (and fiduciarily mandated) corporate ethos, we should expect corps to follow its guiding light to its logical end. As soon as Walmart can stock their shelves with a robot, they will. As soon as McDonalds can reliably serve food without a single worker on staff, they will. As soon as Fedex can roll a Google truck, they will. Human labor is viewed as a "commodity" and it reliably becomes more expensive with time.
I think the mistake that the author makes is that he assumes humans will be part of the machine. They won't. There will be strikes and protests and maybe even legislation, but those will only slow the pace of change, not stop it. The US and Western European economies will look quite different in 50 years. I doubt anything but boutique items will be made even in part by humans. Before then, we will all have to ask ourselves what we do with our time and how do we provide for our needs. The end of the story effectively contrasts two possible outcomes.
