> we brought down image creation time to mere seconds, even for images that were multiple GiB in size<p>this sounds interesting; for e.g., was wondering the other day if we could build images without actually pulling base images.. everytime we compile, we copy artifact(s) onto a multi-hundred MB base image which definitely doesn't need to be pulled everytime.

One of the neat things about something like this is that you could, in theory, do OS builds (think stuff like bootable containers) where you can, deterministically, configure an operating system to boot into all within the confines of your web browser.<p>We already have image builders for stuff like Talos Linux and Incus OS. This is not out of the realm of possibility.

I joked once that the future was dockerizing every single react component and running them in a wasm port of k8s... I hope that premonition isn't coming true!
