ELI5: Am I correcting in assuming that Apples iOS is based on a 7+ year old frame work. How long before they have to completely redo the OS instead of making incremental changes?

As a 5-year old, something you can relate to is Legos. Modern software design is just like Legos. The parts of the program are all built as standardized pieces. They can be taken apart and put back together in a variety of ways, but because of this use of standard parts, old parts can be removed and then new parts can take their place. Those new parts can do exactly the same thing as the old or do things in entirely new ways. Modern software works just like that. Think of how your parent's old 1980's Space Lego set can be put together with your older siblings's Harry Potter set and all of that works with your brand new Chima set.
