The author was the first who patented 3D printing in 1984, based on the voxel by voxel addition of a selected material to a complex structure under construction. Since then, fabrication paradigms advanced so that it is nowadays possible to modify the shape of the objects created in one or more potential fields by modifying the environment. This defines the basic idea of 4D printing and of Bio-printing, which is, in simple words, 4D printing of living things. The lecture will deal with what these emerging technologies represent. It will emphasize their current limits and underpin few ways to break current scientific barriers (complexity), teleology, epistemology and flexible organization in a context where results must be obtained as quickly as possible. The period of “simple” ideas, like for 3D printing in 1984, is over
