Future of Computing Technologies

Michio Kaku discusses the impending end of Moore's Law, which predicts the doubling of computer power every 18 months. He explains the challenges faced by silicon technology, such as heat and leakage, and explores potential alternatives like molecular and quantum computing. Kaku highlights the limitations of current technologies and suggests that while Moore's Law may be tweaked in the short term, new computing paradigms will be necessary in the future.
