- Technology development occurs across four distinct time scales: new research ideas (10-20+ years), hype generation (short-lived cycles), at-scale deployment (software ~20 years, hardware longer), and reshaping the economy (50+ years).
- New research ideas often take decades to mature, with many false starts; for example, neural networks evolved from 1943 to 2012 for deep learning, and another decade for LLMs.
- Hype cycles rapidly inflate expectations but rarely lead to transformative technologies, as seen with blockchain, metaverse, IBM Watson, and nanotechnology; many people confuse hype with real progress.
- Scaling a technology from solid product to mass adoption requires huge effort; Unix/Linux took over 40 years to dominate, and self-driving cars are still not widely deployed despite decades of work.
