Thank you very much for you invaluable help, Bob.
Here is the last part of the same summary.
1) One of the other prominent scientists involved in the promotion of nanotechnology, Richard Smalley, has accused Drexler of ‘scaring our children’ and promulgating a vision of the future based on poor scientific reasoning.
2) As a matter of fact, currently there are no nanotechnological devices capable of self-replication .Yet philosophers, ethicists and many scientists frequently speak as if such objects exist now, or will in the very near future.
3) Other scientist think that the “grey goo” scenario is only a distraction, because people must pay attention on the current practices of science and technology and the need for careful oversight and deliberation that attends to current problem and practices, not imagined future scenarios.
1) Richard Smalley, another prominent scientist involved in the promotion of nanotechnology, has criticized Drexler for "scaring our children" and promoting a vision of the future based on poor scientific reasoning. To understand more about this disagreement, you can research the specific arguments put forth by Richard Smalley and Eric Drexler regarding nanotechnology. Look for articles, interviews, or debates where they discuss their differing viewpoints.
2) Currently, there are no nanotechnological devices capable of self-replication. Despite this fact, philosophers, ethicists, and some scientists often talk about self-replicating nanomachines as if they already exist or will exist in the near future. To learn more about this topic, you can search for information on the current state of nanotechnology and the limitations that prevent the development of self-replicating nanomachines. Scientific journals, reputable websites, and books on nanotechnology can provide insights into the ongoing research and the challenges involved.
3) Some scientists argue that the "grey goo" scenario, in which self-replicating nanomachines uncontrollably consume resources and turn the world into a mass of grey goo, is merely a distraction. They suggest that it is more important to focus on current practices and technologies, along with the need for careful oversight and deliberation. To delve deeper into this perspective, you can explore the debates and discussions surrounding the potential risks and benefits of nanotechnology. Investigate the viewpoints of scientists, ethicists, and policymakers who emphasize the importance of responsible development and regulations in the field of nanotechnology.
