So can we really claim these as MPAs? This is all using the same architecture of SPAs but it moves it to the backend. Technically that's still an SPA that moved the rendering to the server and instead of shipping JSON and telling the browser to update with the new JSON it's the server sending HTML that the browser is told to replace a part of the screen. It's really just the same thing but with a twist. This is not "MPA" tech, it's SPA tech with new bells and whistles. MPA tech (PHP, CGIBIN, etc..) is dead and not coming back.

If the author states this, I would be on board - we're shifting to shipping HTML chunks.
