He feels threatened by the work of the COSMIC DE as this DE will basically offer a smoother end user experience without the caveats of other DEs. Once it is out of it’s Alpha to Stable development cycle, of course. COSMIC will be at a big advantage of not having any legacy code holding it back, and will purposefully avoid a lot of the annoyances of current DEs on the scene. I’ll let the System 76 team cook before passing any solid judgements on COSMIC. There are a few years yet before COSMIC becomes something amazing (I’m just guessing, take this with a grain of salt).
