Would like to clarify a few things:

- This build does NOT run in real time. It runs on MCHPRS, the server developed by StackDoubleFlow, which speeds up the game roughly 10-20,000x while running redstone. That brings the framerate to a much more reasonable 0.1fps, so the long timelapses in the video only took 9 hours to record in total.

- The world download currently in the description is non-functional for two reasons: in order to prevent content thieves such as Steveee immediately stealing it and making a profit, and also because Uwerta and I are currently improving the GUI system to be more similar to normal Minecraft (there's some dissimilarity in how items are moved around in the inventory). I'll update this comment when we release a functional download.

- If you want to learn more about how it works, a brief explanation video is in the description, and that one has links to all the documentation including flowcharts for the GPU and other hardware, and the entire (commented) program itself.

This video talks about Steveee and some others; casual Minecrafters, such as myself can get great benefit in the game by following tutorials, seeing others builds, etc. Naturally, some people make a living developing and making this content (or a little on the side at least.) The low hanging fruit for someone without scruples is just to copy the content outright or the design... Then they can focus their time on publicizing their channel instead of the hard work of original content creation.

It should be noted that using other's work, such as copying a design, is considered generally OK by the community so long as you credit where you got the design from with reasonable prominence.

And yes, we will run DOOM on this hardware at some point, but projects such as these take a long time to create! After all, we are only 3 people working on this in our free time. Have patience until then :)

It feels more like "I wanted to do something silly with arbitrary constraints and it made me encounter all these fun issues and build these interesting workarounds."

Meanwhile, Minecraft videos are too often “Look at the cool thing you can do in Minecraft” which you like me probably don’t care about.

Doing it flat, the only limit is the hardware.

It's not just one big Minecraft map, but several stitched together.

That's a fascinating comment

It would be great to have a list of systems where this already happened. With most neural nets, since they don't ever perceive the effects of their outputs on the world (only the effects of the last version perhaps, say GPT4 seeing/learning about GPT3 output and its effects on the internet), but for some reinforcement learning agents some level of self-awareness might have already occurred.

Going off "510M sq/km" for the Earth's surface area, that gives you about 7 blocks per sq/m. You could drop down to 2x2 blocks per sq/m to give you a 50cm resolution (good enough, I reckon).

But the vertical resolution is awful. Sticking to ~sea level and modelling Everest, you'd get 23m/block which is useless for most things building-wise. If you wanted the Mariana Trench as well, you're down to 50m/block.

(You can change these in your `server.properties` but I've no idea what breaks.)

Bedrock is default 60000000 x 60000000 x 60000000 which gives you the 50cm horizontal resolution and (I think) ~0.3mm resolution vertically.

Clearly an anti-pattern, so clearly these guys have no idea what they are doing
