There are some use-cases that Apple pioneered. After they bought Primesense, who made the first Kinect using quite interesting structured IR laser light points and a single camera to get depth, Apple shrank that technology. It is now the core of FaceID where it does a 3D scan of your face. On the backside of iPhones, Apple is using LIDAR to estimate depth, allowing improved computational photography.

Unfortunately it never caught on in other devices. I'd love a more secure face-id kind of thing in my Laptop (Apple, ThinkPad etc.) that authenticates me.
