Is Fetch.AI for real?

Is Fetch.AI truly legitimate, or is it just another crypto fad? I've heard about its ambitious vision of a decentralized machine learning network, but how does it stand out from the rest? And what are the practical applications of this technology? Can it really revolutionize industries like supply chain management and healthcare? Or is it all just hype without real-world use cases? I'm interested in investing, but I want to make sure it's a solid and sustainable project. Can you help me understand Fetch.AI's underlying technology and its potential for growth?
