Can the large-scale open online course classroom replace the traditional classroom?

Imagine that if a large number of open online courses are used in the classroom in the future, students and teachers are far apart, and teachers can't restrain students, but will let them go with the flow. People have to work hard to work hard. After all, only a few people take the initiative to learn.
