The Planck length is analogous to the pixel. Our parent universe has a much tinier Planck length, and hence it acts as an ultra high resolution monitor, on which it can fit all the pixels of our universe, as well as an abundance of parallel universe simulations, all displayed at the same monitor.
Like our parent simulators, we will need to increase the Planck length for the simulations we create (i.e., reduce their resolutions), so that we can fit an abundance of simulations in our universe and carry on this important tradition. The grand monitor above us will take on a fractal appearance, with very tiny monitors displayed within it.
The turtle on top of all of this — the tiniest possible monitor, rendered with the fewest conceivable pixels — our great-great-great granddaughter simulation — will be blocky Minecraft simulation. The people there will marvel that so much complexity can arise from so few "parts". Perhaps their superintelligence will be able to peel back the layers of their parent simulations to find our Hacker News comments, and their superintelligence will report back to them our words of wisdom. To them I say, "It wasn't easy, kids! Eat your vegetables."
