”As Russell says, you need a whole new approach to prototyping, focused on building something that works with actual data and lets you interactively explore what works in reality, versus the relationships you hope are there from thought experiments….Next time somebody’s trying to sell you on the awesomeness of their new data technique, ask to see a prototype. If they haven’t got that far, it’s snake oil.
