YouTLDR SummaryAuto transcript
You are forgotten when your name is last spoken and your physical traces fade. This happens in stages: your name (nominal ghost), your likeness (figural ghost), your genes (genetic ghost), and your actions' ripple effects (ripple ghost).
- ๐ค Your nominal ghost (name) dies when it's last spoken; the oldest known name is Kusham (5,000 years old).
- ๐ผ๏ธ Your figural ghost (likeness) can persist via statues (Gudea, 4,000 years old) or digital records.
- ๐งฌ Your genetic ghost (DNA) dilutes to ~12.5% in great-grandchildren and ~0% by 11 generations ago.
- ๐ Fossilization is rare (<0.1% of species); rapid, deep burial in low-oxygen, fine sediment offers best chances.
- ๐ Space probes like Voyager's Golden Records could last trillions of years, outlasting stars.
