A new method of construction emerges in the middle of the 21st century. Instead of humans and cumbersome machines, genetically modified bacteria are now working at construction sites. This method is called bio-3D-printing.
The tiny “builders” move along an initially defined route, leaving in its wake natural traces of life. Some bacteria behave according to genetic programming. Others follow electromagnetic fields.
They feed on semimanufactured goods needed to “produce” various building materials. Biologists have already learned to breed different types of microorganisms and find them suitable nourishment according to physical characteristics of target buildings — durability, lightness, color, and other traits.
For now, these buildings are not very tall or complex, and the method itself is very expensive, but experts say that the future is in GMO construction and that we will be able to soon stop using human labor for backbreaking construction. Of course, this will mean further negotiation over “technological unemployment.” But the latest computer models suggest that this may be solved if all human beings get meaningful shares.
