1) Another promiment scientist*
2) as if such devices exist, or will in the very near future.*
3) people should focus on the current practices of science and technology, there is a need for careful oversight upon current problems and practices, rather than imagining possible future scenarios and outcomes.
Writeacher, can you please check if the use of scientific English is OK. Thank you.
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 scientists think that the “grey goo” scenario is only a distraction, because people should focus on the current practices of science and technology, the need for careful oversight and deliberation that attends to current problems and practices, rather than imagine future scenarios.
