Would be interesting. Personally also hate chatbots. If voice would be integrated to the gui with instant reactions it would be cool. But currently these things are to slow. Chatbots depend on what you doing with it. search a document in your paperless? probably better then doing it yourself.
Gui and chat/voice needs to merge with fast gui feedback.
The chart seems logical to me. Most problems are solved in the app space. New apps don't have to be the new facebook. They just need to be useful for the right audience (even a small one). It's like you have meat and bread in the supermarket, and add all other stuff you dont really need. Will be bought, but not as much as meat and bread, right?
