For me, it is unclear what this article is about. Starts out with an image that shows the real wasted time for having a quick meeting. Next discusses a quirky writing tool that will delete everything you write if you stop typing. Then maybe suggests developers be involved in design. Finally, there’s a conference in Paris.
I am interested in the topics brought up in this article individually, but I feel like I might have missed the larger point of the article.
So regarding the title, what was the dangerous mistake and how does it relate to the writing app?
