If it was generative ai being used to slander the people Spain was committing a genocide against, absolutely. Imagine if they had generative AI during the genocide of the Americas and the Spanish were using it to fabricate false sexual assault claims against conquistadors. Exact same situation.
I somehow doubt it. They didn't need to invent the sexual assault crimes against the former IOC chief that first came up with the genocide accusations.
I noticed people like to change the definition of genocide. Because the common understanding just blatantly doesn't fit the situation in any real sense.
