Zen is a fork of Firefox, supports Firefox extensions, and retains the built-in access to the Mozilla extension/theme stores from vanilla Firefox. If you go to install an addon, it even gives a popup to "Add to Firefox".
It's a good browser with only minor issues. I'm on Win10; automatic updates don't always succeed, and it seems like it blocks some communication between the 1password desktop app and the browser extension because I have to sign into each separately. Otherwise, I prefer it to Firefox in pretty much every way.
We went from Deep Dream in 2015: https://en.wikipedia.org/wiki/DeepDream
To Midjourney and Stable Diffusion in 2022, to AI Will Smith eating spaghetti in March 2023: https://knowyourmeme.com/memes/ai-will-smith-eating-spaghetti
To services like LumaLabs and openAI's Sora, coming out now/2025-ish.
This is the equivalent of the spaghetti video, for video games. This Minecraft clone being generated in real time and playable is absolutely crazy.
