Sora was one of the earliest demos of a "wow okay that is good enough to be mistaken for real" GenAI model, which is what that comment was referencing with the "weapon" reference (the tech behind it not just Sora™ Videos).

Sure, by the time they productized it, Sora was no longer SOTA thanks to the AI arms race. And ultimately positioned as a TikTok for Slop with an annoying watermark so didn't take the world by storm on its own.

But since it was unveiled GenAI videos as a whole have become commonplace everywhere else on the internet, with plenty of negative impact already in terms of spam or manipulation, and we're barely in year 2 so far.
