I'm starting to wonder if all this developer time we're saving by using Ruby is leaking out in other places (chiefly, deployment and performance optimization). I'm new to Go, but it seems to me that deployment and optimization are considerably less of a problem while also not costing me much on the development side of things.
I think most of these development worries are more likely related to language independent deployment issues, mostly static assets processing: optimizing images, minifying Javascript, running CSS preprocessors, versioning everything to prevent caching, generating and copying configuration files, other necessary file/folder transformations for creating a running application. Sure the dependency worries are bothersome too, but I'm not sure they're the whole problem.
I'm not sure, I just think it's worth discussing.
