These types of opportunities already exist but are rarely taken up upon. More of them means more jobs unfilled.

When those mining towns were the way of the world people moved around a lot more. It was no big deal to pack your bags and move there. While census data only started being collected from the 1950s onward, it is estimated that ~40% of the population would move in a given year at the hight of the mining booms. Even in the 1950s, when we started collecting concrete data, around 30% of the population would move in a given year. Now only around 8% of the population will move in a given year.

Nowadays there is an expectation that you can stay put. For example, if you watch housing affordability discussions closely you'll notice the theme is always "I cannot afford a house where I am currently located", not "I cannot afford a house anywhere in the world". Attitudes about living arrangements have changed as compared to the past and the AI companies are not about to change it back any time soon. They have to work with people they want to hire, and that means putting the work where the people are already found.
