> Another confusion I have is that if primitive int and Integer merge into Int, then we have problems with null?

The author isn’t suggesting that this would be a design change that would be compatible with the current semantics of Java, so behaviour for null would change.

Yeap.

I can think of two main uses for Integer: when you have type polymorphism (e.g. my own code often has maps of Object) or nullness.

I go on to describe a different approach to nullness that suites ints, for example.
