What problem does cosmos solve?

Could you please elaborate on the specific issue that Cosmos aims to address? I'm curious to understand how it differs from other blockchain platforms and what unique challenges it's designed to overcome. Is it scalability? Interoperability between blockchains? Or perhaps the fragmentation within the cryptocurrency ecosystem? Could you break it down in layman's terms so I can get a better grasp of its significance and potential impact on the industry? I'm keen to learn more about the problem Cosmos is trying to solve and how it proposes to do so.
