What's the backview of sqrt(2)?

One can imagine that

.9999......9999999999

is like a shopping bag with two handles, one on the right (9),
one on the left (9), and an infinite number of digits in between.

One could, if it made sense to think of having a "last" digit when
there are an infinite number of digits in between and the order type
of the sequence is omega.

If my grandmother had wheels, she would be a bicycle. What does that
make my grandfather?

I agree with you entirely. My point in the post was to
focus some intelligent and informed attention on the 'backview'
concept, which it has done successfully:-)

and also BTW on the equally questionable 'frontview'
conceprt for 10-adics.
