Docker isn't really used for desktop applications. Docker also requires a daemon (and on OSX a full virtual machine) to run.

A better analogy for this system would be jar files that allow more languages than just java.

For starters you don't need docker installed, or any container at all. This is largely targeted to end-user deployments where you're providing a binary to users to run, and the current defacto is to make a self extracting exe which dumps all the dependencies along with your executable to a temp directory before executing. Rather messy.

Edit: just looked at the warp implementation, it's a self extractor and executor

This solves some of the app packaging pain that goes into building desktop apps. Not sure how this works but it probably bundles dependencies into the binary a la static linking. Docker mocks the OS and virtualizes, its a very different approach

I'm stoked for anything that eases the pain of desktop deployment that isn't Electron. Right now the cross-platform story is... complicated
