Imagine there was a society in which blue eyed people are referred to with blee/bler pronouns, and green eyed people are referred to with glee/gler pronouns, and one day someone from that society saw a brown eyed person and had no idea whether to categorise them as blee/bler or glee/gler
If you like fantasy, he is writing some of the best out there right now. The Stormlight series is planned as 10 books, 5 so far, so if you want to “try it out” you might want to start elsewhere. His Mistborn trilogy is outstanding, and the first book can actually stand alone so you don’t feel like committing. It’s also got some good social commentary in the world building about class systems etc.
If you don’t like fantasy, then probably not worth your time.
