Review Questions

• How does nanotechnology impact medicine, particularly in the context of drug delivery systems?
  • Nanotechnology significantly enhances medicine by enabling targeted drug delivery systems. With nanoparticles designed to carry medications directly to affected cells or tissues, treatments become more effective while minimizing side effects. This precision allows for better control over drug release, improving overall patient outcomes and potentially revolutionizing how diseases are treated.
• Discuss the ethical implications of using nanotechnology in transhumanism and its potential effects on human enhancement.
  • The use of nanotechnology in transhumanism raises ethical concerns about equity, accessibility, and the definition of what it means to be human. As technologies emerge that could enhance cognitive functions or physical abilities through nanotechnology, questions arise about who has access to these enhancements. There is a risk of creating societal divides between those who can afford such technologies and those who cannot, potentially leading to new forms of inequality.
• Evaluate how advancements in nanotechnology could influence future developments in human enhancement and societal norms.
  • Advancements in nanotechnology hold the potential to fundamentally reshape human enhancement by introducing capabilities such as improved cognitive performance or enhanced physical attributes through engineered nanoparticles. As these technologies develop, they challenge existing societal norms around health, ability, and human identity. The broader implications could result in redefining what constitutes 'normal' human function, leading to debates about ethics, regulation, and the essence of humanity itself.
