NeRF only works with static scenes, requires perfect camera pose, clean scene with clear edges and low exposure. For outdoors any tree with leaves is going to add a lot of noise and blur. For a natural scene indoors the camera exposure is going to be too high. While it is certainly a breakthrough, even “just” static scene reconstruction is still not solved, given the limitations above.

Note also, NeRF is not an “AI” model, it is more of fancy compact storage for objects, images or scenes.
