No doubt the role of the teacher will change in the future, and it would not even have to be a person, I have read that with advances in AI could even have virtual tutors. In some conventional curricula you can see a certain subject with the teacher of the student's choice, and connectivity would allow the teacher to be in another place. Now that, it will always be required to be a teacher because he is a professional with the pedagogical tools, something that an expert in a certain area may not, one thing is to know about the subject and another is to know how to teach about it, believe me that not always the expert knows about teaching methods. And if the expert in the subject dominates the teaching techniques, then he can be considered a teacher. Certainly with autonomy the student is expected to be responsible for his education, being able to look for his own support system, but it will always be necessary that someone guides him and evaluates if he has reached a goal, and that person must be trained for it.
