Idk I don't think the problem is the SPA itself, it's bad design patterns that that make it terrible as you say.

I think really clean, performant SPAs can definitely be written and I think the overall experience of using a SPA can be much better than a multi-page site if the task at hand requires it.

There should be two parts of the web now really: * Traditional multi-page websites * SPAs that could have been a native app on the device, but are much more accessible in web form and without requiring an install
