Build by day, erase by night

Erasing a little every day

Key ideaErase a little, and you can keep building

We store one memory a day in the same network for a whole year. This time, every night all links are weakened by 3%. By day, light flows out from the center to write a new memory; by night, a violet wave passes and erases. Old days scatter like ash, but roughly the last 18 days stay clear all year.

Why?The network that never erased lost every memory on day 59. The one that erases a little gives up old things but keeps taking in new ones. Forgetting is not a fault. It is the tidying that lets us keep adding new things.

Go furtherThe 12 golden dots are memories we bring back often, like days full of feeling. In this model they are recalled every night and written back in by the amount they faded, so they last the whole year. What you see is a small learning network (256 dots, one picture a day) actually being run. A real brain is far bigger and remembers countless things every day.
