And that is wrong. There are all the nodes and all the edges, hence all the paths of the complete infinite Binary Tree  and nothing more.

Both are improper subtrees of each other.

No, my argument cannot fail unless there are nodes beyond any finite level, what you called level aleph_0. But of course that is nonsense. As you don't repeat it, you may have learned it meanwhile. > > The really countable tree that have all its paths indistinguishable > from SOME paths of the CIBT is actually the A_CIBT* (review my earlier > response to you to remember what that is).

There are not uncountably many finite (initial segments of) paths. And also any antidiagonal can only differ from other paths in its (and their) finite initial segments. Unless your silly idea of nodes at level aleph_0 was correct (it is not) there is no chance to differ at other places than finite (initial segments of) paths. But that is impossible if all of them are already there. And the latter is possible, because they form a countable set.
Stop claiming uncountability unless you can find a node that make a finite initial segment actually infinite.
