Good point, the depth first search algorithm is a bit lack luster for this case: 1 -> .1 2 -> .01 3 -> .001 4 -> .0001 5 -> .00001 6 -> .000001 . -> .0∞1

I would definitely recommend not judging the quality of the video based upon the quality of my reasoning in the experiment.

That would only count the rationals which you can definitely count off a carefully arranged matrix of rationals. But reals = rationals and irrationals and the irrationals are uncountable.

You are definitely right, I missed quite a few numbers in this set. (Thank you!)
