the "stellar mesh" idea aims to sit beside the web.
It should provide similar capabilities to what makes browsers able to execute untrusted code - sandboxing & limited system access - while freeing us from the constraints forced on us by mid-90s technology stack decisions. https://twitter.com/TrevorFSmith/status/1299023513416736769

a 'runnable' would be the equivalent of a 'document' on today's web - where the web serves a document that we've been strapping applications onto, the stellar mesh serves an application.

Importantly, this means that we are not tied to the DOM

granted, today most 3d web applications just have some barebones HTML around the canvas / webgl renderer. We think we could skip directly to serving the 3D runtime, and cut out the middle part of attaching it to a document.

part of the intent is that we don't want to have to rely on the benevolence / desires of the mega corps that currently control browser implementation, and to a large degree, web standards.

We should be able to reap many of the benefits of the web model, in a platform that is:
simple enough to be re-implemented
flexible enough to allow many different 'engines' to run on top
focused on the needs of interactive applications first, especially real-time 3D
