I just LOVE your podcast and delicious repartee. I do wish you would take more care in the use of the term/formulation “infinite.” I see it as the unending PROCESS of continually adding, decreasing, etc., to an amount or a function. E.g., an “infinite” velocity represents non-sense (“distance”/“time”) by definition. An infinite “anything” is not a finished amount, but a label for an ongoing operation the WE perform. IMHO, of course
