> And how many of those applications allow for a human being to be removed from the workforce?
Oh, I did not try to argue with you. I just assumed, based on your first line that you were not aware of all the things that AI is being used in the corporate world. But bottom two links are cases where workers are being removed. And it is not like this was a full list of what AI has done, it was just a few examples. If you were not familiar with any of these, I can guarantee that you are not aware of hundreds of other examples there are.
> it looks like it will take highly technical staff just to have the capability to review the AI returns to confirm if they're even workable or not
Yes. If you (or the AI you are using) find a new mathematical solution, you will need a mathematician to verify the result. Then you need some kind of circuit engineer to implement that algorithm into a chip. After that consumer can just buy those chips and take advantage of faster computation power, or in this case, the company can get the benefit of selling and using better TPUs. But while you need a human, you only need it once. Once the new algorithm has been verified and taken into use, that human work is no longer needed.
> so far it doesn't look like the people who fall into the vast chasm of nontechnical "office workers" are under immediate threat from AI.
What does a nontechnical office worker do? Journalists? Some of those tasks have already been to AI or even simpler algorithm. Duolingo at least was going to replace some tasks with AI. But generally problem with these non-technical office jobs is that they are often easily replaced with a simple script. I personally once created a script in week, which replaced a full time worker, who was later fired as there was no other work left for him to do. And I know people who use an external calculator to count the sum of values in their Excel worksheet, every day.
You could probably count the sum in Excel already decades ago. Yet some people still do "manual" calculations, simply because they don't know how to use their tools. So it is not like we need a new technology to replace people.
So I predict that this is not how AI will replace half of the population. Instead, AI will make scientific discoveries, like invent cure for everything and this in turn, will cause massive job loss for doctors and nurses.
