In my humble opinion, SPAs are not the fundamental mistakes. SPAs are applications. There's nothing wrong with having applications. The mistake was not maintaining a distinction between applications and content. The difference between a static document, a collection of hypertext documents, and a web application is very blurry. If it were less blurry, there would have been things we would have been able to do that we are not currently able to do.
