AI is large enough a field to warrant a new, dedicated track. In practice, as of current times, AI R&D/academia are enabled (perhaps even fueled) largely by the "traditional" constructs of computer science.

In my opinion, as time goes by and advancements are made, the coupling should grow weaker - and so we'll reach a point where there would be a more clear distinction between the two tracks, and they won't share much of the same curriculum, similarly to where we stand today with CS and electrical engineering.
