I never could figure out the point of Objects.
The point of objects is to support data abstraction by disallowing any
old random code in a large system from directly manipulating the
innards of the objects, and instead require that to be done by methods
declared to be part of the object.
Every data type is different.
If that weren't true, you'd only need one kind of object.
Perhaps what you're questioning is inheritance, which is useful but
isn't necessarily a required feature of objects. Inheritance is based
on the idea that while two types aren't identical, they may have
similarities. As a trivial example, integers and floats are different
data types, but they both support arithmetic. from the device class.

[1] A class is the definition of an object. Or in other words, an
object is an instantiated (created) class.
