Part of the value of push-based systems is that each node only needs to keep track of its own dependencies and dependents, which makes analysing each node locally easy, but analysing the system as a whole hard. In the extreme case, you might dynamically create and destroy nodes in the tree depending on previous values — this doesn’t make sense for our spreadsheet analogy, but is essentially what’s happening with RxJS’s switchMap operator. Essentially, the more dynamism we want in our system, the harder it is to achieve efficient updates, and the more we want efficient updates, the more we need to specify our dependency graphs up-front.

Starting with the Nothing Phone 4a, which we've seen (abundantly) at the Mobile World Congress (MWC) in Barcelona, it has a 6.78-inch, 120Hz, AMOLED display, a Qualcomm Snapdragon 7s Gen 4 chip, 8/12GB of RAM, and 128/256GB of storage. On the back, there's a triple camera system with a 50-megapixel main camera, a 50-megapixel periscope telephoto camera with 3.5x optical zoom, and an ultrawide camera (for some reason, the company does not provide details about it), coupled with a 32-megapixel selfie camera on the front.
