Subscribe * * * Hi friends 👋, Happy Tuesday! Welcome to our newest installment in what has become an unintentional two-part series on non-LLM models that can do things that humans can’t, things that will give us superhuman abilities in the physical world. They’re also both co-written with founders you’d expect to find in SF but are building right here in the greatest city in the world, NYC. The first was last week’s essay on World Models with Pim de Witte. Today’s is about machines that can intuit electromagnetic fields in a way almost no humans can that will help us design and build better electromagnetic (EM) systems.

As you know, I’m very bullish on the growing role of electromagnetic systems in the economy. After Sam and I wrote _The Electric Slide_, Arena Physica CEO Pratap Ranade and I traded emails. In one of them, he wrote: > _The electrical and electromagnetic components are the “nervous system” of modern hardware and contribute to 40-50% of failures. Our ability as a nation to test and build it has declined, but –– imo even bigger –– as a species, we’re still unable to wield electromagnetism to its full _ Over the past seven months, we’ve developed a friendship, and Pratap has broken my brain many times.
