What problem is Cardano solving?

Could you elaborate on the question, "What problem is Cardano solving?" It seems intriguing to understand the specific challenges that Cardano, as a cryptocurrency platform, is addressing. Is it about scalability, privacy, or perhaps interoperability with other blockchains? Or does it tackle issues related to governance, sustainability, or the decentralization of finance? I'm keen to know the exact nature of the problem Cardano aims to resolve and how its unique features and technology contribute to this solution.
