There's something very obvious which creates a major difference between a jubilee or oxford debate and a debate craft debate, and that is, time boundation. Here on debate craft one can take a lot of time, can collect more data and arguments, or even use AI. There's no burden of a real discussion. We can have these fast paced debates, where intellect and communication are the real factors very easily. We can have Voice Mode debates(with or without camera for privacy reasons) , people can fix a particular time for a debate. The Audio Recording may remain there for voting for 24 or 48 hours. Definitely Audio Recordings are quite Big in size, to manage storage issues, we may only allow a few people to use this feature. There can be a proposal for debate, which if gets enough votes(let's say 5) then it can get a fixed time window on a day to be discussed. There can be a hard limit of 2 debates in a day.
This is highly realistic, it's feasible, very efficient and very original above all. Only Discord has a feature like a voice room, which can be used as a debate room. No other online platform, or any other platform has a voice room specifically for debates.
