It's all a smoke-screen. It shows that Google (and every other big tech company) is producing super secret, super high tech stuff that should make their shareholders super happy. The reality is that Google and co haven't produced shit for years, have laid off hundreds of thousands of people worldwide, and don't have long term plans to improve outside of enshittifcation.
Yeah but big tech is also the customer. So it doesnt make sense. How will they make money if the only way to do so is to trick other giant tech companies into buying and using your product?
