Yup, Google has the attention span of a gnat. I've used Pixel Phones for years, and I wouldn't be even slightly surprised to see that entire product line dropped tomorrow. I'm very glad to see Apple's Vision Pro, because I believe that if it succeeds it will be wonderful, and if it fails it means the AR/VR product category will never (well, not for a very long time at least) be anything but an unimportant niche product, as it is now.
I wonder if it is because of how its promotion package works. A middle manager thinks up of a product and executes in it. It launches, the manager get a promotion, and then it gets kill for not getting enough users. By then the manager got their pay raise and no longer needs the project.
