How to estimate it
Fermi’s official “Napkin math”
The first summit was back in 1953, about 70 years ago. Hardly anyone made it in the early decades, but lately it's hundreds a year. Average across all of it, maybe 100 a year.
- Years since 1953
- ~70
- Summited per year
- × 100
- 70 × 100
- ≈ 7,000
Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.
