Jack Dorsey says Block employees now bring prototypes, not slides, to meetings (businessinsider.com)

Block CEO Jack Dorsey said the company has shifted from slide decks to bringing prototypes to meetings, arguing prototypes offer more realism and can be updated in real time. He said the cost of making the wrong decision is becoming smaller, and linked the change to a broader tech trend away from presentations. Dorsey also cited AI-driven efficiency amid Block’s earlier layoffs.
