There is still something small popping up all the time. Every week if not every day something surprises, you can say. I read more detail about Ashoka, I realized gel with unsweetened juice and erythritol is a great desert, things like that. You think you know everything about food, and you come accross gelatin and realize you had missed it.
The last major surprise to me was when I found that bitcoin is a perfect money, and that all the right world changing people had found it (if not founded it), too.
