Nice and fun talk with some stuff to think about!
It's a great talk brought by a great speaker. I would definitely recommend to watch this talk when possible.
Jeroen brings the subject in such a way, that people from all levels would understand. So many times talks are brought as the next silver bullet, but Jeroen can convince everybody that our profession isn't that black and white. There is no perfect solution that works everywhere. There is not abstraction that should always be used. There is no single talk that provides all the answers, that even includes this talk ;)
Very nice talk, thanks! The examples of the code bases not showing what it does was nice. Maybe you could include an example of where it actually is clear from the file structure.
