Michio Kaku has a blueprint for a time machine. You just need the energy of a star. Then you hit the grandfather paradox.

Time travel with Michio Kaku on Hanselminutes.

How to build a time machine

Back in 2008, Michio Kaku told me Moore's Law would hit a wall around 2020. Chips so hot you could fry an egg on them.

Did he call it? You tell me.

Moore's Law has an end date

Michio Kaku says kids get hooked on science between 10 and 16. Miss that window and you may lose them.

As a parent, this one stuck with me.

Six golden years for science

Many worlds says there are copies of you in billions of universes. In some of them, Elvis is still alive.

Michio Kaku also says there's a non-zero chance you wake up on Mars tomorrow.

Somewhere, Elvis is still alive

Forget one giant Enterprise. Michio Kaku says we could send billions of nanoships to a star instead.

Nanotechnology, one atom at a time, from my chat with him on Hanselminutes.

Billions of tiny starships

Why don't we have Star Wars ray guns? Michio Kaku says the physics works. What's missing is a power pack powerful enough to hold in your hand.

Yes, I brought up my laptop battery.

Why we don't have ray guns

In high school, Michio Kaku built a particle accelerator in his garage. It blew every circuit breaker in the house.

Then I asked what he wrapped the wire around.

He built an atom smasher at home

Kat does not want to look at code after 5. She says that is normal, and it is not a character flaw.

You do not have to code after 5

Kat Excellence walked me through why she chose a CS degree over a bootcamp. Student-only internships, a broader education, and a network that reaches Big Tech.

Why Kat picked college over a bootcamp

Kat uses career envy as a signal. If someone's path makes you jealous, that is data about what you want.

AI isn't just changing how we write code. It's changing how we build software, structure teams, and think about what it means to be a software engineer. In this episode of Hanselminutes, Scott Hanselman sits down with Sunita Verma, CTO at Ironclad and a longtime Google engineering veteran, to explore why simply adding AI tools to existing development workflows isn't enough.

They discuss the shift from writing code to directing AI agents, why traditional sequential software development processes may need to evolve, and how smaller engineering teams can compete with much larger organizations. How do engineers adapt when writing code is no longer the primary measure of productivity? What happens to collaboration, ownership, and engineering judgment? And can AI actually reduce burnout, or does it just raise expectations?

What happens when the laws of quantum physics meet computer science? In this special crossover episode of Hanselminutes and ACM ByteCast, Scott Hanselman sits down with Charles H. Bennett and Gilles Brassard, recipients of the 2025 ACM A.M. Turing Award, often called the "Nobel Prize of Computing."

These two pioneers helped lay the foundations of quantum information science, revolutionizing how we think about computing, cryptography, and secure communication. From their groundbreaking work on quantum key distribution to the surprising possibilities of quantum teleportation, Bennett and Brassard explore the ideas that helped launch an entirely new field of computing.

Join us for a fascinating conversation about curiosity, collaboration, quantum mechanics, and what happens when fundamental research changes what's possible.

A young man who's a sophomore in high school emailed me to come on his podcast that he does with his friend, and I had so much fun. I decided to make it a crossover episode. Check out "Compile after Class" on this week's episode!

Compile after Class Crossover Episode

Felix Rieseberg came to computing through poetry, and that background gives him a unique lens for explaining language models. A longtime engineer, Felix now gets to watch AI evolve from the inside. In this episode, Scott and Felix explore why language models are surprisingly easy to understand despite feeling magical, what it's like to train a model from noise to coherence, and the bigger philosophical questions about intelligence that AI keeps surfacing. You can learn how AI really works by making your own in a weekend with his free site below.

Maynard Holliday spent 30+ years at the intersection of robotics, nuclear security, and defense technology, most recently serving as the Assistant Secretary of Defense for Critical Technologies. He's worked on everything from helping remediate Three Mile Island to securing tons of Soviet nuclear material in post-Cold War Ukraine to overseeing the Pentagon's critical technology portfolio including AI, hypersonics, and microelectronics. He shares what "trusted AI" really means, why he co-founded Black in Robotics, and how T'Challa and Tony Stark shaped his career more than you'd expect.
