I also wish I had AI in college. I would have used it to descramble the unintelligible utterances of the calculus lecturers who had minimal or no English language skills.
For example, I hated English growing up and then I had a college English course with a professor who was absolutely passionate about it and made it fun. Now, I hate English a little less and could appreciate it more. We need more people like that for other subjects.
I'm positive that college lecturers fall below this baseline, but there's plenty of alternatives that a moderately motivated student could use.
Part of the problem is that the typical ~20 year old student has little idea how to learn something and little opinion about what their education should produce, to guide them.
