Sure, I meant to make the point that developers are drawn to SPAs for more understandable reasons than just being a bunch of lemmings.

Also, it's hard to realize how much work a SPA actually entails until you get your hands dirty. SPAs generally sound great on paper from a technical standpoint.

If you have a mobile app, you need an API, even if you‘re site does not function as an application.

The great majority of websites, though, DON'T need a mobile app; they need a website that works on mobile. Most smartphone users are unwilling to download more than a few apps for websites, anyway; if your website is a restaurant, a news source, or anything else that works well on a website, most users are unwilling to download and install your app anyway. So, if you want their business, you need to make your website work for mobile. Once you have done, that, in most (not all) cases, you don't need to develop an app anyway.

unless you use Turbolinks with IOS/Android adapters or another hybrid app alternative
