The degree, which is a requirement at many jobs.

Becoming independent for the first time in one's life.

Meeting new people from different backgrounds and exposing oneself to new ideas.

The experience, which many college students enjoy.

Etc.

In any case, I doubt AI is going to replace educators anytime soon.

For AI to be as valuable as a teacher/tutor/professor, it would have to essentially be perfect at educating, and perfecting AI takes a FAR, FAR longer time than making it good (a level that some would argue AI hasn't reached yet in the educating realm, despite tools like ChatGPT being as impressive as they are).

Never mind that a lot of education is hands-on, so you have to be present at a school/campus/etc. with a human educator to guide you through that.

Also, take into account that not all knowledge taught at schools is on the internet, which is where AI learns from.

Given these reasons and others, I don't really see the education system being disrupted anytime soon, but it will definitely change.
