Meaning: The quote you provided is from K. Drexler, a scientist known for his work in the field of nanotechnology and molecular engineering. In this quote, Drexler is discussing the state of research and development in the field of building complex molecular systems. He suggests that while there are academic and industrial groups working on relevant projects, there is not a significant emphasis on the construction of complex molecular systems. Drexler then goes on to rank Japan as first, Europe as second, and "we're" (presumably referring to the United States) as third in terms of focus on this particular area of research.

This quote reflects Drexler's perspective on the global landscape of molecular engineering and nanotechnology research. To understand the context of this statement, it's important to explore Drexler's background and contributions to the field. K. Eric Drexler is a prominent figure in the field of nanotechnology, having popularized the concept of molecular nanotechnology through his book "Engines of Creation" published in 1986. He is known for his visionary ideas about the potential of nanotechnology to revolutionize various industries and address complex challenges.

Drexler's assertion about the prioritization of building complex molecular systems suggests that he sees Japan as a leader in this area of research. Japan has a strong reputation for its advancements in technology and innovation, and it is plausible that Drexler's assessment is based on specific projects, initiatives, or research institutions within the country that are particularly focused on developing complex molecular systems. Similarly, his placement of Europe in the second position indicates that he views European countries as also making significant strides in this field. It's worth noting that Europe has a robust scientific community and substantial research funding, which contributes to its competitiveness in cutting-edge technological research.

The statement's conclusion that "we're third" implies that the United States, from Drexler's perspective, lags behind Japan and Europe in the focus on building complex molecular systems. This observation may be surprising given the traditionally strong position of the United States in scientific research and technological innovation. However, Drexler's assessment could be based on his perception of the specific research priorities and investments in molecular engineering and nanotechnology within the United States compared to those in Japan and Europe.

It's important to recognize that Drexler's viewpoint represents a specific moment in time and may not reflect the current state of affairs in the global landscape of molecular engineering and nanotechnology research. Research priorities and investments can shift over time, and different countries may emerge as leaders in specific areas of technological development.

In conclusion, K. Eric Drexler's quote highlights his perspective on the global focus on building complex molecular systems within the context of nanotechnology and molecular engineering. His ranking of Japan, Europe, and the United States reflects his assessment of the relative emphasis placed on this particular area of research within these regions. While the quote provides insight into Drexler's viewpoint, it is essential to consider it within the broader context of the dynamic and evolving field of nanotechnology and molecular engineering.
