clojure.core is automatically interned when a new namespace is created?

It depends. Yes if you use (ns foo) ..., but not apparently if you use
Unless you have a very compelling reason, just don't use use. It's mostly a
historical accident that's kept there for backwards compatibility.
And try to avoid :refer :all if possible. There are legitimate use-cases
for it, but outside the REPL they are pretty rare.

For example:
(:require [clojure.java.io :as io])
vs
(:use [clojure.java.io :as io])
In both cases, we can end up using it with (io/function name ... ). Is
there a difference at all?
Thanks

Yes, (:use [clojure.java.io :as io])
Ok, so require without :refer will default to :refer :all?

No.
(:use [clojure.java.io]) is equivalent to (:require [clojure.java.io :refer
:all])
There’s no :as here. :use is like :require :refer :all.
(:use
Ah, I see. I thought “use :as” will not intern all the symbols into current
namespace, apparently that’s not the case.
Thanks for clearing this up.

Not quite, (:use [clojure.java.io]) is equivalent to (:require [clojure.java.io
:refer :all])
