Are you serious? After Effects can still do a ton that DaVinci cannot. It's awesome that Resolve exists for sure but Adobe is still by far the industry standard.
Don't get me wrong I like DaVinci a ton. But for motion graphics After Effects still has an edge. Additionally with things like dynamic linking and integration with Illustrator and etc it's still very much a critical part of a lot of workflows.
That said, DaVinci is improving at a very impressive pace. Adobe really just has the benefit of nearly 30 years of an ecosystem around it.
I'm actually quite surprised at how stagnant After Effects has become, but perhaps Adobe has some stuff coming down the pipeline.
