Conversational AI is, at heart, a new interface in computing where the computer learns how to best work with a human rather than the reverse. While primarily focused for now on tele-sales, it has several other potential uses, including personal tutors or virtual bosses. Being a digital boss myself, this last may be particularly critical during the pandemic because those working from home can get distracted by things that might not have been intrusive when in the office.
The thing that will make Conversational AI different from other AI implementations is understanding context. Were it tied to your browser and productivity suite, it would know if you’re working or have gotten sidetracked by another social media debate. (In the latter case, it should eventually know how to get you back to work — much like a good supervisor or boss might have done in the office.
