**📅 Date:** ➤ ⌈ [[2025-06-12-Thu〚LSD ▪mTor ▪ 🦖 Dinosaurs vs 🧍‍♂️ Humans〛]]⌋ **💭 What:** >[!note] #👾/Comment >When reflecting on [[SuperHuman ⁰¹ - Bryan Johnson -The “Don’t Die” Ideology|Bryan Johnson’s]] question about how people 500 years from now might perceive us, I can’t help but confront my own _P(doom)_ — the probability that humanity may not survive that long. In evolutionary terms, we are still a very young species. Modern humans have only been around for ~300,000 years, and our civilizations span merely ~10,000 years. Dinosaurs, by comparison, thrived for 165 million years. This contrast serves as a humbling reminder of both our fragility and our potential. Our current moment represents only 0.006% of the timespan that dinosaurs occupied. It’s from this perspective that I see the importance of the “Don’t Die” ideology — not only for optimizing individual longevity, but for reducing _P(doom)_, building existential resilience, and extending humanity’s arc for millennia to come. >> We are infants on this planet. Dinosaurs thrived far longer than humans have existed so far. Our fragility is real — but so is our potential if we successfully navigate existential risk (P-doom, AI risk, climate risk, etc.). **👀 Snap:** ➤ Estimations for life on Earth is about 3.7 billion years. All of human history is roughly 0.008% of that time. To put it in perspective if the estimations for life on Earth were condensed to just one year then humans have only been around for 42 minutes. ⇩ 🅻🅸🅽🅺🆂 ⇩ **🏷️ Tags**: **🗂 Menu** ⌈[[Super Human 2005 ⁰⁰- MOC| SuperHuman 2025]]⌋ ⌈[[✢ M O C ➣ 06 ⌈J U N - 2 0 2 5⌉ ✢|2025 - J U N- MOC]]⌋ ⌈[[✢ L O G ➢ 06 ⌈J U N - 2 0 2 5⌉ ✢|2025 - J U N - LOG]]⌋ #👾/Private ------➤ ⌈[[🦖The "Longevity Bottleneck" Hypothesis]]⌋ ------➤ ⌈[[SuperHuman ⁰¹ - Bryan Johnson -The “Don’t Die” Ideology]]⌋ ------➤ ⌈[[Super Human 2005 ⁰⁰- MOC]]⌋ ---   ### 🦖 Dinosaurs - **Total existence:** ~165 million years. - **Time period:** - Originated: ~230 million years ago (Late Triassic). - Extinction: ~65 million years ago (end of Cretaceous period). - **Extinction event:** - Likely caused by a combination of: - Giant asteroid impact (Chicxulub event). - Massive volcanic activity (Deccan Traps). - Climate changes and ecological disruptions. - **Legacy:** - Birds are considered the only surviving lineage of dinosaurs. - Dinosaurs dominated Earth for nearly 80x longer than modern humans have existed. --- ### 🧍‍♂️ Humans - **Modern Homo sapiens:** ~300,000 years old. - **Hominin ancestors (early bipedal primates):** ~6 million years ago. - **Human civilization (organized societies, agriculture, writing, cities):** ~ 6,000years ago. > [!info] Modern civilization is extremely recent on the evolutionary timeline — roughly 0.006% of the time dinosaurs ruled the Earth. --- ### 📐 Timeline Comparison | Species | Duration (Years) | | ------------------ | ---------------- | | Dinosaurs | ~165,000,000 | | Homo sapiens | ~300,000 | | Human civilization | ~ 6,000 | --- ### 🧮 Percentage - fe on Earth: ~3.7 billion years (~3,700,000,000 years) - - **Dinosaurs existed:** ~165 million years (from ~230M to ~65M years ago) - Modern humans (Homo sapiens): ~300,000 years - All of human civilization (since agriculture, cities, writing, etc.): ~10,000 years Estimations for life on Earth is about 3.7 billion years.
