Computers by nature have absolute recall. If we want them to round off numbers, we have to program them to alter the data to do so. Some savants (idiot and otherwise) do have total recall of numbers. Most humans do not. That means that there is probably a gene that determines this talent. Eventually, parents will be able to select genes for their children, or at least that technology will exist. Being as there are over 200 countries on the planet, it is likely that parents can BUY those genes, even if "designer genes" are banned.
Robots do not need to pass a Turing test to paint cars, wash clothes or vacuum the floor.
