Paul Atkinson was invited to be a guest speaker at the Interactive Design International Symposium held at CAFA in Beijing. The symposium was based around Interactive Media Design, which on the face of it, might not be too relevant for the issues raised by Post Industrial Manufacturing. The point of the talk, though, was to show how the increase in amateur involvement in design enabled by new open source technologies is not only a good thing for design, but is also inevitable, so we might as well deal with it. Failure to engage with these technologies risks professional design becoming at least partially redundant. The issues raised, therefore, are relevant to all areas of design, not just three-dimensional design.
