I did sort of touch on this in the essay when I wrote:

"If these experts insist “I’m only willing to educate you on a Zoom call, I’ll educate you via video” then I have the option of hiring any expert in the world, I don’t need to hire an expert in the USA. If I need to educate myself on a set of technologies, so as to evaluate competing software architectures, then I would prefer to meet with experts in-person, but if for some reason I had to rely on communication via Zoom or Slack, there is no reason for me to hire someone in the USA. In such cases, the only reason I would hire a remote worker in the USA is if they were the greatest expert in the world on a subject that I wanted to learn. "

But I go into much greater detail in my book. I devote a whole chapter to this in my book.
