Key concepts: Chapter One - The Harbinger
1. Chapter One - The Harbinger
Personal Origins and Early Computing
- Author's first computer encounter in 1979 Lusaka, Zambia
- Sinclair ZX81, Acorn BBC Master, and PC clone progression
- Ten-year leap showed thousands-fold power increase
Moore's Law: Mechanics and Impact
- Transistor counts double every 18-24 months at same cost
- Cost per transistor fell from $150 to billionths of a dollar
- Self-fulfilling industry pledge, not a physics law
Exponential Technology Defined
- Improves above 10% per year for decades
- 10% annual gain yields 2.5-fold per decade
- Drives dramatic price drops and capability explosions
Technology Adoption S-Curves
- Slow start, steep exponential rise, then plateau
- Social media reached 70% in 11 years vs electricity's 62%
- Smartphones diffused 12.5 times faster than telephones
Accelerating Diffusion in Digital Era
- Facebook hit million users in 15 months
- TikTok exploded from obscurity to dominance in months
- Moore's Law directly enabled this acceleration
Moore's Law Hits Physical Limits
- Transistors shrank to atomic scale causing quantum leakage
- Fabrication plants cost over $15 billion
- Transistor density growth sputtered by early 2000s
Law of Accelerating Returns and AI Revolution
- Overlapping S-curves keep overall progress exponential
- ImageNet and AlexNet sparked deep learning in 2012
- AI compute grew 300,000-fold, six times faster than Moore's Law
