The problem a lot of developers have with SPA is that they literally shove the entire app into 1 page load. Which is where most of their problems come from. If you use a hybrid approach. Have the data you need to show the page right away cached in the html and then load any other data after while that page is being used. And you break the app up into multiple pages. It works perfectly fine. It actually makes it super easy to hand out work to a team of devs and minimizes stepping on each other.
