Why will Cardano fail?

I've been hearing a lot of buzz about Cardano, but I'm skeptical. Could you explain why Cardano might fail? It seems like there's a lot of hype surrounding it, but I'm wondering if there are any fundamental flaws in its design or execution that could lead to its downfall. Is its scalability an issue? What about its competition in the crypto space? And what role does regulation play in Cardano's potential failure? I'd really appreciate it if you could break down these points for me in a clear and concise manner.
