Honestly it's too early to know.
Also, schools are in the business of imparting knowledge and schools in the U.S. are extremely expensive. Any parent knows the additional fees, supplies etc most schools demand on top of their taxes that go to the school district.
If you take the daycare aspect out of it, a $500/mo ChatGPT subscription is noise by comparison. A student doesn't have to be lucky to have a receptive teacher that has enough office hours and the interest to help the student. ChatGPT is available 24x7. A teacher takes days off, falls sick and has favorites.
If AI enters the school with full force, bulk of the teachers are likely going to be replaced by various care staff.
There will still likely be some human assistants around who will be the new "teachers" but the current format of everyone staring at a whiteboard is going to change forever in this future.
The concept of "grades" (as in K-12) are also likely going to go away replaced by cohorts, simply because every student has their own "teacher" who understands their specific needs and can pay them all the attention they need assisted by a human adult.
One child can be in one cohort for English and an entirely different cohort for Math.
