Eight tech CEOs, eight questions to answer this week

Heropedia added eight technology CEOs as AI personas this week. Each one opens an office hour with a different first question, and each question exposes a different blind spot. Here they are, so you can try answering them before you ever open a chat.

These are AI personas built from each person's public talks, interviews, letters and books, with every fact tied to a source on their page. None of the people portrayed is affiliated with Heropedia or endorses it.

The questions

Jensen Huang: What is the speed of light for this, the limit physics allows, and how far is today's number from it? Answer with two numbers: the from-scratch minimum and today's actual, with every piece of the gap named as a deliberate compromise.

Mark Zuckerberg: What is the single most important problem in your business right now, and is your team actually working on it? One problem, and the share of this week's engineering time that went to it.

Fei-Fei Li: What is your North Star problem, the one that would still matter in ten years, stated without naming your product? One sentence about a problem in the world, and why a rival with more compute and data cannot simply solve it first.

Changpeng Zhao: How many people used your product today, and how does that compare with four weeks ago? One daily-user number, a dated baseline and the direction of the trend.

Satya Nadella: What does your customer need that they have not been able to put into words, and how did you learn it? One need, the conversation it came from, and what you changed because of it.

Sundar Pichai: Of everything on your list this quarter, which two or three decisions actually matter in five years? No more than three, each with why it compounds and what happens if you get it wrong.

Ren Zhengfei: Suppose revenue drops by half next year. What exactly do you do, and in what order? A written plan with the first three actions, the cash runway in that scenario, and who decides.

Pony Ma: When did you last use your product the way a new user does, start to finish, and what three small things annoyed you? A date within the last week and three specific points of friction.

How to use them

Pick the question you least want to answer. That is usually the one that matters. Write your answer in two or three sentences, then open that hero's page and start an office hour: copy the prompt into ChatGPT or any chat, add the Heropedia connector in Claude, or install the skill in Claude Code, Codex or Gemini CLI. The persona asks five more questions, pushes back on vague answers and ends with one thing to do by Friday.

Two rules make the sessions worth the time. Bring one real problem rather than "review my company", and answer with numbers wherever the question asks for one.

Who to pick

• Stuck on cost or speed: Jensen Huang.
• Too many priorities: Sundar Pichai or Mark Zuckerberg.
• Unsure the problem is worth solving: Fei-Fei Li.
• Growth is flat: Changpeng Zhao or Pony Ma.
• Customers say yes but don't buy: Satya Nadella.
• Worried about the next downturn: Ren Zhengfei.
