About

The host & the project.

I'm Mikkel Svold. For most of my career I've been obsessed with one question: what would it take to actually understand the world we've built – physically, biologically, economically – instead of just reacting to it?

Big Ideas Only is my attempt at an answer. Each episode is a slow, serious conversation with someone who has spent a decade or two thinking carefully about a single problem. The articles on Knowledge are companion essays – written for readers who want depth without jargon.

No hot takes. No clickbait. No pretending complicated things are simple. Just the big ideas, treated with the care they deserve.
