Part of it is about how much you need to investigate to have a well-informed opinion-- in this case, about the condition of a science.
Part of it is about, even though there are research-blocking incentives, there are also a lot of people finding ways to work against those incentives and do research, presumably because there are a lot of people who really want to do research.
And a list of recent discoveries-- I assume things are so lively because the tools keep getting better and biology is so complex that there's a tremendous amount to use the tools on.
