I have had a great deal of experience finding and correcting
arithmetical errors in boring papers.

Does TO claim that the infinite numbers of Robinson's non-standard
analysis are in any way connected to the transfinite cardinals and
ordinals of Cantor's analyses? Pray tell what ultrafilter generates
standard cardinals and ordinals in the way that ultrafilters are needed
to construct Robinson's non-standard reals from standard reals.

There is a lot of schlock about but it is all of TO's generation.

Almost always, as far as the meaning of standard mathematical terms goes.

Isn't that precisely what TO's various alternate number systems do,
declare something out of nothing?

So that every time a child references Santa Claus or the tooth fairy
they come into existence?
