[Cthulhu_]

From what I remember from spring boot it is (or feels like) more of a system to assemble your application from discrete modules, but which modules are used for what can be determined by configuration and various rules.

I mean the use cases of that will be limited these days; application architectures have changed to the point where what used to be a module within a Spring application can now be a microservice to be enabled or spun up depending on rules defined outside of the application.

But this is a very superficial point of view, I haven't seriously touched Spring for a decade and, thanks to some experience with Go, I feel like I won't need to either for most modern-day applications.

While Go may not be for everyone or for every application, its mindset of keeping things simple, just use the SDK or some libraries, etc does make for better developers. IMO.
