I think Mycroft was unfortunately just ahead of its time. STT was just becoming good enough but NLU wasn’t quite there yet. Add in you’re up against Apple Google and Amazon who were able to add integrations like music and subsidize the crap out of their products.

I just think this time around is different. Open Whisper gives them amazing STT and LLMs can far more easily be adapted for the NLU portion. The hardware is also dirt cheap which makes it better suited to a narrow use case.
