The whole first section: 9 features, 9 titles with "AI" in them.
I don't think their use of it is bad at all, I'm just tired.
You're right to be tired of it, and of course I haven't tired these specific features yet, but Davinci was already lowering the barrier to entry for filmmakers, and if 21 works as they say it will, then you're looking at a major lowering of said barrier.
They could remove the word "AI" from each one of those feature titles, and the titles would be just as descriptive without them. At this point, it's just marketing noise, more distracting than informative. Maybe like "cyber" in the 1990s. Would you like some AI tea with your cybercrumpets?
