Lenny Rachitsky: It's interesting that so much of this conversation is this and the way you think about building this company is this balance between practical, useful things people need and business and practical stuff, and then the value of building something you're proud of and craft. And there's always this trade-off almost of speed and quality, and I know that's an important element for you. Just thinking about trade-offs between decisions, so talk about just trade-offs, just how you think about making a trade-off. Ivan Zhao: Yeah, I think this is quite relevant especially for product makers and business makers is there's no free lunch. You don't get something for free. You have to give up something. Then what do you give up? It's essentially you give up the right thing that market or your user wants at that given space and time. It's just the craft of building a business or building a product. And that the market is so dynamic, especially now with AI. The optimized function for the market changes so then you need to make new trade-off and new technology emerges. I always feels like AI language model feels like a new type of wood. It feels like aluminum. It's a new type of material. So you can make... Mass air travel wasn't available until aluminum become cheap enough that people can make airplanes that support this at cost. And it's like computer wasn't there until semiconductor becomes... It's like require new technology to unlock new way to making trade-offs, and then you need to balance the technology trade-off with human behavior trade-off.
