Veo 3
The newly-published video Impossible Challenges (Google Veo 3 ) by demonflyingfox is both an amazing showcase of Google's new Veo 3 AI (to be fair, I'm sure there was post-production) and hilarious commentary on the kind of algorithmic bullshit YouTube is constantly manipulating creators into publishing.
edit (2025-12-30): Although I was sure there had to be post-production when I published this, I'm no longer sure. If there was, there wasn't necessarily much. Sora 2 shows that this technology really is that amazing.
