You're right, though I didn't mean just the editing latency. For web projects, the latency is now between me and some dev server in the cloud vs localhost, and for CLI as well. For GUIs or anything that interacts with my OS (such as "applets") or my hardware devices now I have to download the program to test it.

For web projects, I understand that latency should be considered, but I've learned what's important there and don't want to build/compile/minify my projects in development so I'm wasting time downloading the same MB's of JS over and over when only a few bytes changed so I'm not getting cache hits.
