Some people are also talking about how slick BeOS was twenty years ago and asking why current operating systems are not like that, without realizing that the gap in functionality and support for advanced hardware and security features (for example) is huge. Every year we can do more and more with our phones and apps but all that functionality comes with bugs and a maintenance burden, because developers are human.
It's not really an issue, you can switch off automatic updates if it causes you stress, but be aware of security implications. Also you don't have to sit through an update, let it install overnight or while you do something else...
