I think devs forget how efficient and blazing fast server rendered pages can be, and ultimately what a great user experience non-SPA applications can provide. It seems like the dev community has locked in on SPAs for everything. There is so much complexity and other overhead associated with SPAs. At the end of the day a browser is rendering HTML + CSS, JS can handle some additional interactivity. Presently, we have some very complex SPAs that are handling large amounts of state, large dependencies (js libs), often optimized assets, etc. I remember people bemoaning Flash apps. I kind of feel like SPAs are kind of becoming the new Flash app.
