Last week a senior citizen asked me if there is any simple course on basics of Artificial Intelligence and all the new technology buzzwords for them to catch up on. I immediately pointed them to the YouTube channel Crash Course's playlist on these topics. And to my surprise, they finished watching all these videos over the weekend and even made notes about it :) they loved these simple animations with crisp and easy to understand explanations of complex paradigms.

I like to think that 'learning' is one of the fundamental needs of a human, and everyone, regardless of their age, wants to learn something all the time. The popularity of a topic or the subject, the depth/width of interest, or the media may keep changing. So if you keep the venture capitalists point of view aside, there will always be a huge audience for your course or learning product. And the only secret sauce for success is figuring out how well do the learners learn it and stay invested till the end. YouTube channels like the Crash Course, Kurtzgesagt, or even simple whiteboard teaching of Abdul Bari, seem to have figured it out so well. Sales, marketing, and tech are only supportive functions for scale.

If you know something good enough and can communicate it effectively, please consider taking up teaching as a side project/hobby, if not as your profession.
