Next you are going to want little endian polynomials, and that is just too far. Also, the advantage of big endian is it naturally extends to decimals/negative exponents where the later on things are less important. X squared plus x plus three minus one over x plus one over x squared etc.

Loss of big endian chips saddens me like the loss of underscores in var names in Go Lang. The homogeneity is worth something, thanks intel and camelCase, but the old order that passes away and is no more had the beauty of a new world.
