Why are constant firmware updates a thing?

I dont mind. My ps3 froze on me several times in the early days. With each update it become less regular and I dont force shutdown my ps3 in more than a year, so changes and improves were made and I don't mind the few minutes here and there...
Ps4 is way better because some games froze but the OS never freezes, and the updates are one minute things, awesome thing...
