Just watched your videos and they’re great! Please keep making them 
For me, the hardest part about OTP is not the syntax (how to use it), but understanding why and more importantly when to use it. So I really liked the package delivery example, as it helped me understand how everything works. Maybe you could go back to that example in a future video and show how it would be done correctly? Or maybe also show some other use cases for GenServers or even what a full supervision structure could look like?
Thanks again
