I have listened to this whole series. It is a very high quality set of videos. IMHO, it is the best one out there explaining core AI concepts especially some fairly advanced ones systematically, and in a format that is more friendly to younger learners. Part of the videos are even great for 2nd and 3rd graders. However, the challenge is many of the core AI concepts naturally require fairly advanced knowledge in math (high school and beyond)  to truly understand. It also needs to be combined with hands-on coding exercises for students to see what the concepts really mean.  So, teachers need to curate it and take the pieces of the videos that are age appropriate for their students and combine with other materials.
