Using them for everything and everywhere as a default option might have been a mistake. SPAs in general are not a mistake (but generalised headlines do bring in the clicks so there's that).

As a user, when I'm using an "application", on the web or the desktop, the last thing I want is for the entire UI to be reloaded for me after every action. For applications it makes sense to be run on a single page, fetching only the data when it's required and that's it.
