We're quickly reaching the point where Lidar isn't needed, pure vision workflows are getting much better.

No, it very much depends on the application, what you're trying to do. Different tools for different jobs. Don't conflate.

Well, Elon thought that too and we still haven't seen any robotaxi

LiDAR in drones is not necessarily the "stereo vision" application you are thinking of, it can also be something as simple as a LiDAR altimeter.

yeah, who could ever need accurate and immediate depth perception, having to carry a 4090 in my roomba to badly reconstruct it from 4 pictures so it can stop bumping into walls is like the future man
