The clueless ninny writing at Metapicture says:
Watch what it can do and then remember this was all done with hand tools.
Young people who have never been in personal contact with the production of physical objects and who have been brought up to believe in the Whig Theory of History and the notion of Coueist Technological Progress inevitably suppose that machines can do everything better. In reality, if you want real precision, you build it with hand tools.
