Interesting but it would be nice to bring some code examples
In a presentation that is so theorical some code examples really would help, it was hard to follow without examples
It seems he was a bit vexed about the first presentation at phpbc2015 because it was defined "rad" as "bad". He exposed his point of view about the term and put a great example of a fast developed API. I think rapid development is just a good usage of yagni not the usage of tools to go fast. Very good presentation though.
Incredible to see how someone can think different and to try DIY. This way you'll learn a lot for sure. But this guy should have a lot of spare time :p
The was something that I maybe could find on YouTube. I could not get the point of it unless the idea was to present his own component for creating API with scaffolding.
I was not expecting this kind of talks in a conference.
