I'm not sure exactly how the future of GT will fare being a public school. A large reason for the lead was how early the school established the College of Computing.
Will private schools end up a better place to study CS due to their smaller class sizes and less variance in the student population? I can't say for sure due to not personally knowing what studying at those private schools is like, but I think large lecture halls are ineffectual as a continued method of higher education.
Another phenomenon is the amount of international students who come to the USA and are so focused on the idea and prestige of working for "Big Tech." Then they get there and find out how expensive the rent is, how expensive college was, and they spent all their time doing leetcode (which actually has some interesting fundamentals if you get really into it, it's not my thing personally though) and now graduate and think: now what?
