Ya and leather can also scratch and get worn areas too. Everything will wear with use and lack of upkeep, but I wouldn't discount alcantara solely for fear of wearing out.I did read that (leather is more durable if kept conditioned) in at least one of the articles I researched. I have no experience with Alcantara, but I do know that some leather steering wheels get sticky over time.
The fact that you're even concerned about it tells me you're probably the type of person who cares for their things.
