I have some thoughts on the future of #UI on non-mobile devices and the role that #FLOSS can play.
1. It seems that all proprietary software companies are de-prioritising their desktop OSes, in terms of focus and resources. Microsoft is doing weird tablet hybridisation and Apple is just porting iOS junk back from the iPad.
This creates a vacuum, as there is no modern desktop UI. Nothing's been done since roughly OS X. It's been 18 years. More than my whole adult life.
