Mycroft is an open source artificial intelligence platform (an open source assistant) and has very nice demos like: Mycroft Plasmoid Version 2.0 and Akademy 2017 presentation (this one starts around 2:30) .

The problem with packaging this is that the dependency tree is LARGE, not so much for the plasmoid (whose dependency tree I don't think will give any problem since most, if not all of it is already packaged) but Mycroft Core has a lot of dependencies missing (and those might have even more by themselves), so I plan to work on this during hackweek and learn how it integrates in the desktop, so by the end of hackweek users can install Mycroft easily on Tumbleweed.
