Not apparent at first, but this is a TypeScript to c++ compiler at the core (https://github.com/geastack/compiler), with bindings for various platforms.

Nice.
I will keep an eye on this for future use.

What do they use for graphics and audio?

They mention OpenGL for the bigger targets, but I was wondering how this worked for the ESP32. Turns out they wrote a custom 2D rasterizer specifically for this target, basically a miniature version of a browser layout engine: https://geastack.com/blog-we-taught-a-chip-to-run-css

Each platform has its native bindings. For graphics, you write CSS and HTML canvas API as well as JSX, it renders to native components and their alignments, the canvas API is converted to native surfaces, whatever the platform uses.

I mean, is it OpenGL, Vulkan, Metal? etc...

It defers to platform defaults, Android compositor, UIKit/AppKit native views or CoreGraphics for the canvas on Apple platforms, GDI/GDI+ on Windows, whatever SDL2 chooses on Linux. If you have a Three.js app, it uses Metal on iOS and macOS, Direct3D 11 (open) and 12 (commercial license) on Windows and XBox.

It's not clear at first glance, but given (1) the apps are written in JavaScript (2) the project has repos for different OS native bindings, my bet is some kind of embedded JavaScript engine that just calls through to OS native widets

It compiles TypeScript statically to C++, there's no JS engine or VM running.

Ah this is for embedded apps. Pretty neat!

It also supports iOS, macOS, Android, Windows, Linux, XBox for Three.js games, as well as (some) Node.js apps.

could you throw a react project (WEB) at it and get a native macos project out of it?

It supports Gea frontends (https://geajs.com). Technically it could compile React with a plugin, but that is left to the community as an exercise :)
The code is on GitHub, for example for the first video that renders a 3D cube with CSS the code is at https://github.com/geastack/examples/tree/main/apps/css-3d-c.... It takes only a couple of CLI commands to get it running. For reference, I'm using a WaveShare ESP32-S3 AMOLED Touch 2.06" device here, but the same code renders on every target Gea compiles for.

"The earlier implementation could not be driven to zero of them, because boxing was load-bearing in its emitter"
I see what you’re getting at, but let’s not pretend like “load-bearing” is something that AIs made up. It was a turn of phrase long before AIs became mainstream and people are still allowed to use it.
I will keep an eye on this for future use.
