Kirby's a UGA grad and still relatively young. He'll probably still be coaching after Nick's departed this life. He took what Mark Richt had built, which was good-to-really-good, and made it better. AND he's maintained the standard. AND he exorcised the Saban curse.
I expect UGA to take another title in waaay less than 40 years. More like single-digits.
I do not live in SC any longer. How obnoxious were the GA fans there? Having lived in Ohio for 8 years, OSU fans rival Gamecock fans in stupidity and annoyance. I know GA fans used to be horrendous and almost inbred in behaviors, yet it seemed that 40 years calmed them down. To answer the question, until Ga gets a team that plays better than the ACC Coastal division in the SEC Least, they only have to win one or two games to qualify for playoffs. So there is a chance, but Kirby gonna kirby.
