Learn that natural numbers are integers are ordinal numbers are cardinal numbers (at that time not yet existing, in letters appearing not before 1886, in papers not before 1892*) are rational numbers are real numbers are complex numbers are vectors are matrices are tensors.
Your objection is absolutely silly. You could analogously accuse me of discussion with Alan Smail but not discussing with human or not discussing with an intelligent being.
Im an interested in your reaction which probably will clarify the last point.

(*) There is a letter from Cantor to Curd Lasswitz of 1884 mentioning Kardinalzahl sveral times. But it has turned to be a fake by Zermelo
