Episode notes
Brain vs. Computer
- Human brains are not fully understood, making direct comparisons with computers difficult.
- Computers rely on separate memory and computation units, unlike the brain's interconnected layers.
Computer Abstraction Layers
- Computer engineering uses abstraction layers, from atoms to data centers.
- Building computers involves various disciplines and understanding these layers.
Found Parallelism
- Modern computers find about 10x parallelism in code.
- This involves predicting branch directions with high accuracy using complex methods.
