Why do posthumans choose not to run ancestor simulations?

Posthumans are like super-smart wizards who can build whole worlds inside their computers, but sometimes they don’t want to run ancestor simulations because it’s like having a big, messy room full of toys and not wanting to clean them up every day.

Imagine you have a robot friend that loves playing with blocks. Every time it plays, it makes a huge pile of blocks on the floor. But cleaning them all up takes forever! So sometimes, your robot just says, “I’ll play another day,” and leaves the blocks there for now.

That’s kind of what posthumans do. Running ancestor simulations is like playing with blocks, it helps them learn about how humans lived long ago. But doing this a lot takes up a lot of their computer power and time. So, they might choose to rest for a while or focus on other fun projects instead.

Sometimes, they even say, “Let’s do this later!” and save the simulation for another day when they have more energy, or more block-cleaning power!
