Please make your T-Bot smarter. Might be integration with Cortana.
T-Bot cannot answer simple question like
1. How is weather today?
2. Who is CEO of Microsoft?
It should work like a like Virtual Assistant so that it can make things easier or more simple like organizing meetings or starting a chat with the someone from your contacts. All the task performed by voice instead of typing. Make it like Cortana but more of T-Bot which specific to the Teams Application.
