jQuery days make me like React, but it's not because I like SPAs, it's because it gives things an intuitive and reusable structure that I can organize and maintain much more effectively and can pretty much be the same server and client side. React is even a comparative pleasure to use for building static sites. I've always assumed SPAs were partially driven by it historically being difficult to combine server side and client side rendering with a single shared code base more than anything - so much of the early stuff ended up in people essentially having to maintain two entire sites between front and back end rather than just one.
