I think everyone is positioning for 2030, 2034, and 2036 (unless CFB goes nuclear, then all bets are off). I think in 2029/30, the B1G will renegotiate their contract for 6 years to coincide with the end of the ACC contract and that a handful of schools will leave. I think there will be schools that will leave the ACC for the SEC in 2036 and the SEC will proactively negotiate their 2033/34 contract to expand in 2036 for the ACC schools that will be joining. But, all ACC schools will remain in the ACC until 2036 (unless someone tries to buy out a year or two like Texas and Oklahoma did). These dates are just too close unless it all blows up (which I think is quite likely to happen).
Georgia Tech is positioning themselves to compete at the highest level. It remains to be seen what that means. I doubt Cabrera will be president when all this happens. CEO's don't usually stick around 15-20 years.
