Good talk tough concepts explained in a clear way
Great talk even after years using phpspec still Duarte surprise me everytime
Extremely interesting and it was exciting to hear the changes from a core developer because he could talk about the intricacies. Even though it is not applicable to my day to day I really enjoyed the talk
The best point was made on the last slide: 'Complex systems require a temporal model'. I think the presentation would have more impact for me, if this point was made sooner. Other than that probably interesting for developers who have limited 'business' experience.
No idea of the context of this, not clear what I can do with this and why is useful
Interesting, thinking out of the box and a fresh new view on designing systems. Very entertaining aswell.
