I choose to interpret "genre giants" as "contributing foundational works to SFF," so I& #39;m going with Le Guin, who used SFF to explore social and political issues when the genres were considered a bit of a joke. She expanded SFF& #39;s possibilities and gave it the respect it deserved. https://twitter.com/blacksailbooks/status/1305539484839223296">https://twitter.com/blacksail...

Many people think SFF is only about mages, space fights and all that weird "woo woo" stuff. Don& #39;t get me wrong, I love pure woo woo. But Le Guin saw its potential to explore universal experiences that expanded our idea of what kind of stories SFF was capable of telling.

There& #39;s no doubting Sanderson& #39;s contemporary popularity; it& #39;s valid to see him as a "giant" depending on your interpretation of that term. But the potential Le Guin gave SFF over a lifetime of writing is enormous.
