> Not only that, but extending these UIs will take more time in the future than their SSR versions due to the added complexity of the front end frameworks
FE is a vibrant ecosystem and the tooling, in my opinion, is some of the best I have worked with as a SE.
Not necessarily, you can have simple and modular front-ends while also having less complex back-end frameworks. The question is between SPA and non-SPA web applications, not between SPA and JSP/PHP.
There are benefits and things you can do with an SPA that you can't do with pure SSR, but they _do_ come at a cost. TANSTAAFL.
But I agree, that seems to be my impression. Single Page Apps allow higher quality User Interfaces (if done right), though they do require more work.
But if the comparison is with more traditional SSR sites, React and Vue are also not doing everything the back-end was doing before.
