Well the finitists at least not walking the path of Merry Poppins, stop dreaming do science, oh wait i forgot math isn't science it is philosophy. Well then proceed on your dream journey and let me talk to people who do real math within the computational theory field. Still looking for the wiz of Oz Tonio.
