Thinking On Paper

What would a gamer do with a quantum computer? Or a musician? Harry Kumar, co-founder of Moth Quantum, thinks quantum computing needs creativity to push quantum forwards, so we're going to find out.

Moth built Quantum Backrooms, a video game where a quantum computer builds the maze. Each tile on the map is a qubit. The correlation between two neighbouring qubits decides whether a wall stands between them. 

However, the game shows no quantum advantage and runs no faster than a game on a classical computer. It certainly isn't GTA6. So why build it? 

Early AI. Image generation no better than a child. But millions of people signed up. That's the step before commercial value. People are creative, they want creative tools. Using quantum for material science and protein synthesis is incredible, but it doesn't bring in the masses. 

Which is why Harry is waiting for quantum computing's Dylan-goes-electric moment. 

We also cover:
How Atlas, Moth's platform, lets you run an image through a quantum computer without writing code 
Whether a musician could hear the difference between quantum and classical randomness 
Which kind of quantum computer makes the best beats, and why Harry won't say
Why Feynman's idea of a computer that works like nature excites artists 
Why Harry won't let AI write his first draft 

Please enjoy the show.

Data centers use water to cool air, not chips. The water chills the air that gets blown across the racks, and that is where it evaporates. Remove the air and you remove most of the water.

Simon Jesenko runs Iceotope, which builds cooling with no fans and no air at all. Fifteen to twenty litres of refined oil circulating inside a sealed chassis, touching every component. His point about the headlines: they describe air-cooled facilities, and the industry is moving off them. Once a site runs fully liquid-cooled, he says consumption drops immensely.

He explains:

- Why direct-to-chip cooling only solves 80 percent of the problem, and what stays hot
- What the dielectric liquid actually is, where it comes from, and why Shell and Exxon make it
- Why early liquid cooling installs leaked, and what that did to the industry's appetite for risk
- Why the power supply unit, not the GPU, is where his technology wins
- Why crypto miners proved immersion cooling years before data centers

Nathan Silvernail quit SpaceX to make wood from grass.

Building the first part of a rocket SpaceX ever reused - the nose cone - wasn’t enough. After a decade working for Elon Musk, he quit. 

Took everything he had learnt.

And started Plantd. 

The plan? Make carbon-negative engineered lumber from fast-growing perennial grass. Climate tech meets space tech. 

Wood, without trees.  

Plantd's panels replace OSB, the oriented strand board that sheathes the floors, walls and roofs of almost every new American home. 

In this hotly anticipated episode, Nathan joins Thinking On Paper to talk about his SpaceX journey, why he thinks Mars is a distraction from the work in front of us, how the lumber industry accounts for the wood it burns, and why building a material stronger than steel turned out to be wrong. 

You’ll get insight into the nine-month harvest cycle, what it takes to change the culture of an industry without letting it notice, and why he believes the unit economics that let SpaceX displace ULA will do the same to timber.

Please enjoy the show.

We read the National Space Transportation Policy in full. Signed 20 August 2026, it shreds the 2013 directive and rewrites how the US gets into space, moves around up there, and comes back down.

The War Department is all over it. Launch ranges, reentry infrastructure, a clause about accommodating launches within 48 hours of need. You don't build a 48-hour capability to do science. Somebody expects to lose a satellite and need a replacement up fast.

Here's what we think stops it. Not rockets. Not pads. Demand. Most of what goes up is Starlink, everyone else crams onto rideshares, and a target of 1,000 assumes five times more reason to be up there than anyone currently has. The document is a sales pitch with the government as a customer.

We also get into the Mars carve-out and what it says about who America needs, the ISS retiring the same year and China’s plans to land on the moon.

Why do we stop asking questions as adults? Philosopher Pia Lauritzen has analysed 30,000 of them, and says nothing was ever lost.

The ability stays. What changes is the price. Every question admits you don't know something, and nobody gets promoted for ignorance. Ask in the wrong room and curiosity starts to feel like an interrogation, which is why most of us learn to keep the question to ourselves.

She proves it in keynotes. One minute, two rules, and every person in the audience writes one. They could do it the whole time.

Be curious, stay disruptive.
