Things to come - possible futures for electronics

1) Ray Kurzweil predicts that computers will soon be able to replicate and surpass the human brain in performance. However, models of biological processes are still at an early stage, so this prediction is likely overly optimistic. 2) Moore's Law of increasing transistor density on chips is expected to continue, though the underlying technologies enabling it may change from 2D scaling to approaches like 3D stacking. 3) Sustaining Moore's Law faces challenges from rising costs and physical limits of silicon technology. Alternatives like 3D stacking, new materials, and biomimetics may extend progress.
