Why is the Amex Black Card so special?

Could you elaborate on the uniqueness of the Amex Black Card? What sets it apart from other premium credit cards? Does it offer exclusive benefits or privileges that are not available with other cards? Are there any specific perks or incentives that make it particularly attractive to high-end consumers? And what are the qualifications or criteria required to obtain such a prestigious card? I'm curious to understand the full scope of its exclusivity and what makes it so sought-after in the world of luxury credit cards.
