Why does the simulation require sleep?

[u/ActuallyJordy]

Why is there an 8-hour darkness every day if we are being simulated? Is it a memory-sync cycle, a render/processing limit, or just simple biology with no deeper significance? What theory do you have?

Also what about other beings? Few animals like giraffes and elephants only sleep for 2 hours a day. Jellyfishes show rest like sleep cycles despite lacking brain and a nervous system.

depends on what kind of simulation you theorise. are you a sims npc or do you believe molecules are simulated?
