The only thing I said is: there are probably no _obvious_ mathematical certainties in reply to what you said, as the history of mathematics shows with plenty of examples."

There is nothing more obvious and certain mathematically than the fact that exponential growth of bubbles entails increasing valuations and increasing rates of growth in those valuations.

I use the word "obvious" quite properly as in "can be read from any graph", or "is contained within the structure or the model". I use categorical because the implied conclusion of the original comment is a categorical error.

There are people who disagree. Here is one compilation of theorems that are obvious and false:
