Susan Kare joined Apple as an art history PhD who barely knew anything about computers. She went on to design many of the icons, typefaces, and symbols that helped make the original Macintosh feel understandable and human, defining a visual language for personal computing that still influences software today.At Startup School 2026, Susan shares the stories behind the Happy Mac, Command key, Chicago font, and more, along with the design lessons she learned from Steve Jobs, Paul Rand, and the original Mac team: make things meaningful and memorable, embrace constraints, iterate constantly, and use just enough detail to make an idea instantly clear.Transcript: https://www.ycrootaccess.com/p/susan-kare-on-designing-the-original

Robots can already fold laundry, make espresso, clean kitchens, and assemble things. The harder problem is getting them to do those tasks reliably, for long periods of time, without a human babysitting them.

At Startup School 2026, Physical Intelligence cofounder Chelsea Finn explains what it takes to build general-purpose robots that work in the real world. She shares how reinforcement learning pushed robot throughput up 2x, how their systems can run autonomously for hours, and why she believes robotics is entering its GPT era: moving from specialized models toward general-purpose systems that can work across tasks, robots, and environments.

Science is building a retinal implant that restores vision to people who have gone blind. One patient has already used it to read a 300-page novel.Building a company like that requires a lot more than getting the technology right. At Startup School 2026, Science CEO Max Hodak explains how the company buys things and hires people, and why those systems determine how fast it can move.He also gets into why founders can’t delegate their judgment, and why there’s no set of five bullet points that makes a startup work.Transcript: https://www.ycrootaccess.com/p/max-hodak-there-are-no-blanket-rules
