Good luck. People will not be able to control their Sonos, listen to their music, use banking apps or check their social.

Not having enough the right apps killed blackberry, windows mobile, windows phone, symbian and palmOS. But sure, a chatbot will be different.

It would have worked 10+ years ago, when we had open apis and could connect to services without being forced into their walled gardens. But now? Nah.

Edit: typo and clarified apps
