For example, progress in genetics is already leading to the development of significant applications, many of which are stirring controversy. Materials and manufacturing breakthroughs are less visible but are key enablers of other fields of development. Nanotechnology trends are mixed between well-developing semiconductor and microsystem technologies, and others that rely on more uncertain basic research developments. The researchers noted that while the technology revolution will expand significantly by 2015, its effects are not proceeding without issue and controversial impact. Various ethical, economic, legal, environmental, safety, and other social concerns and decisions must be addressed as the world's population comes to grip with the potential impact these trends may have on their cultures and lives.
Biotechnology appears to raise the most controversy.
Protests have already erupted over moral and ethical issues surrounding human cloning and the use of stem cells from human embryos to treat disease. Widespread fear over genetically modified foods is spreading across the globe and may suppress further developments in this area. The ability to genetically manipulate species also raises the real concern that human eugenics programs will be initiated. Breakthroughs such as DNA analysis and genetic profiling are already raising privacy concerns. The ability to collect detailed biological information about a person, including their genetic predisposition to certain diseases, invokes certain issues and uncertainties.
