Commercial AI tutoring platforms provide direct instructor substitution at scale
#1A well-funded, rapidly scaling ecosystem of AI tutoring platforms is directly commercializing the core instructional function of this occupational category. Khan Academy's Khanmigo (deployed to millions of students), Duolingo Max (50M+ active users), Coursera's AI coaching suite, Chegg's Cheggmate, and enterprise platforms like Docebo AI and Cornerstone's AI coach are providing on-demand, adaptive, personalized instruction across academic and professional domains. These platforms are not supplements — they are positioned as primary instructional delivery systems, and adoption data shows learners are substituting rather than augmenting with them.
