Define interesting.

I was helping a few people on getting started with an Android Development bootcamp and just being able to run the default example and get their bearing around the IDE was interesting to them. And I remember when I was first learning python. Just doing basic variable declaration and arithmetic was interesting. Same with learning C and being able to write tic-tac-toe.

I think a lot of harm is being done by making beginner have expectations that would befit people that have years of experience. Like you can learn docker in 2 months to someone that doesn't even know Linux exists or have never encountered the word POSIX.
