What does a BrainChip actually do?

Could you please elaborate on the functionality of a BrainChip? I'm intrigued to understand how it operates and what specific tasks it's capable of performing. Is it a hardware device or software-based? Does it have applications in various industries, or is it tailored for a specific purpose? How does it compare to traditional computing architectures in terms of efficiency and performance? I'm particularly interested in its ability to process data and perform complex computations, as well as its potential impact on the future of AI and machine learning.
