AI certainly will be incorporated into different DeFi platforms. That is already taking place to some degree. The idea of implementing oracles using on chain data is a prime example of how this will work.
As for the hype, there is little reason for the AI. We can see how AI is expanding. It is a matter of people getting involved and focusing where they put their data (i.e. build databases). Of course, most will focus upon tokens and market pricing believing that is where one can get an idea of value.
It isnt.
