A tiny intro before you land.

Not the loudest technology. Not necessarily the most technically insane breakthrough. But the products that make AI feel usable, visual, guided, and almost stupidly easy.

Gradium just raised $100m to sell a technology it already open-sourced. Is that genius, or a warning sign?

General Fusion is going public via SPAC. Read the press release and it sounds like a milestone. Read the SEC filings and a different picture emerges. This is what the deep tech funding trap actually looks like — and what it signals for the fusion sector.

Etched came out of stealth with working racks, a successful A0 tapeout, more than $1bn in customer contracts, $800m raised, and a bold thesis: the next AI bottleneck is frontier inference, not just model training.

Fusion already works. Fusion power does not — yet. This piece maps the engineering stack, funding landscape, reactor architectures and 68-company ecosystem being built around the gap.

This piece lays out the physics — why fusion produces energy at all, what conditions trigger it, and why sustaining those conditions has taken the better part of a century to get close to right.

A beginner-friendly breakdown of orbital data centres: why AI is pushing the cloud toward space, the physics and economics behind the idea, who is building it, and why free sunlight still comes with a brutal invoice.
