"At the end of the day, I compared my modules — written in Java — to my Spring XML files. The modules are significantly smaller and easier to read. Then I realized about 3/4 of the code in my modules was unnecessary, so I stripped it out. They were reduced to just a few lines of code each.

Guice wholly embraces annotations and generics, thereby enabling you to wire together and test objects with less effort than ever before. Annotations finally free you from error-prone, refactoring-adverse string identifiers."
The "smart people" are often, in hindsight, horrifyingly incorrect. Look into the history of eugenics and phrenology at some point.
