ELI5: Why is leather still such a popular luxury item for things like upholstery?

Hasn't science created better fabrics by now? Is it really luxurious considering it isn't rare with hundreds of thousands of cows being slaughtered daily? 

I was watching some show where the guy was showing a $20 million Leer jet and he kept going on about the leather. You have this amazing piece of technology that has only been available for 50 years and you're excited about the pieces of dead cow skin that has been used for thousands of years. 

I eat meat and using up the leftover skin makes economical sense, but I don't get why it's the premier fabric of luxury.

Leather is extremely durable, and a lot of people find the look, feel, and smell of it pleasant. It's been in continual use for thousands of years because it's just a great material. And the synthetic materials you mentioned are all petroleum derivatives.
