I think a lot of developers seem to be taking the same approach with bots. They are trying to create alternative UIs for their already existing mobile apps through bots. Mobile / web apps do a lot of the same stuff as bots in a much more user-friendly way. Take a look at https://storebot.me/ and tell me if there's one bot that can do something better than a mobile app.
I'm not anti-bot but I just think the bot-frenzy is premature,
