Meaning: The quote by Anthony Holden reflects on the significant changes in the public's perception and discussion of certain subjects over time. In this instance, Holden is specifically referring to the transformation in the conversation around a particular topic, presumably one he has been writing about for nearly two decades. The quote suggests that the shift in attitude and awareness regarding this subject has been remarkable, particularly within the last five years.

Holden's remark hints at the idea that the public's awareness and engagement with certain topics can evolve rapidly, even after prolonged periods of relatively stable discussion. This could be attributed to a variety of factors, such as advancements in technology, changes in societal attitudes, or the emergence of new information that reshapes the narrative around the subject.

Over the last two decades, the digital revolution has significantly impacted the dissemination of information and the way people engage with various topics. The rise of social media, online news platforms, and digital communication has enabled widespread sharing and discussion of ideas, often leading to rapid shifts in public opinion and awareness. This could explain the drastic change Holden observes within the past five years, as the digital landscape continues to shape and accelerate societal conversations.

Additionally, societal attitudes and values are constantly evolving, which can influence the way certain subjects are perceived and discussed. As people become more informed and receptive to new ideas, the discourse around specific topics can undergo substantial transformation in a relatively short period. This may be what Holden is alluding to when he mentions the astonishing change in the climate surrounding the subject he has been writing about.

Furthermore, the emergence of new information or events can also catalyze rapid shifts in public discourse. Scientific discoveries, geopolitical developments, or cultural movements can all contribute to altering the way people think and talk about particular subjects. Holden's observation may reflect a response to such catalytic events that have reshaped the conversation around the topic he has been immersed in for two decades.

It is also worth considering that Holden's quote could be applicable to a wide range of subjects, including but not limited to politics, technology, social issues, or cultural trends. The pace of change in public discourse varies across different topics, and Holden's experience could be a testament to the dynamic nature of societal conversations in general.

In conclusion, Anthony Holden's quote encapsulates the idea that public discourse and attitudes toward certain subjects can undergo remarkable transformations in a relatively short period. The convergence of technological advancements, evolving societal attitudes, and the impact of new information all contribute to the ever-changing landscape of public conversation. Holden's reflection serves as a reminder of the fluidity and dynamism of societal discourse, and the need to continually adapt to and understand these changes.
