Thats a really bad tl;dr as it make the typical mistake of thinking we need general AI for this to be a reality. But the fact is that most people don't use all their human capabilities to perform the part of their job that is valuable and so AI doesn't need to be as good.

The economic cost is only a matter of time and the larger transition is already happening. Every time a company looks at how to improve productivity they will look more and more at automation.

You are making the mistake of looking at now and saying see it's not that good and thus missing the point which is that technology is exponential and will continue to be so. Even if there was a limit to the CPU speed the connectivity of things will provide a better and better datasource for machines to learn more and more on top of.

Of course there is no precedent thats the whole point. This is the first time machines are actually competing with what we normally thought required highly trained people. We now know it doesn't and you will be hard pressed to find a job that isn't soon going to be possible to replace with some sort of AI or completely disregard it because it's been digitalized away to some other process.
