Dr. Kaku is a great speaker. He’s very inspiring, dynamic, and engaging. Here’s what he has to say about what the world will be like in 2030. He says “physicists” invented all of the things he lists: the internet, the transistor, and many other things, but that’s not totally true.
Dr. Kaku: Romance-physicist. That’s not to say he’s wrong about any of this.
The engineers who invented those things (and the computer scientists who coded the internet) used physics principles to do these things. They were, in a way, physicists. But at their core, they’ve all been engineers and computer scientists. Because that’s who drives the future.
