Because for the last 10 years, “code schools” and boot camps have taught JavaScript/Typescript with React as “programming” where everything outside of your immediate dom is an api call.

Now we are seeing reimplementations of it in various forms to “solve the api call hell” that was self induced. Just like the front-end bundle size problem was self induced.
