New extinction events are arising. My view is that some of these things existed and we just did not know about them. The threat level is not rising by that much, we are just getting a more accurate picture of the actual threat level. I also think that technology can make civilization more robust and better able to survive. So technology is creating new dangers, but is also creating new protection and solutions. Also, it is not just technology but processes and better understanding of what is happening.
For example, we are safer from disease from drugs but also because of access to clean water and sanitary conditions and public health management.
