I do think that they might have some usability in the future when the AI and voice recognition becomes better and we deploy more IoT around our houses, atm most are too expensive and aren't that great, mycroft is quite expensive if you don't build your own, it's $100-$150, but if you build your own it's much cheaper and it's a fun project to do during the summer... and who knows, if you can program more stuff into it you might be able to improve it to the point where it's actually really useful and you might even get paid for doing it.
