In that introduction to the previous update to the book, you can see the authors are responding to critics who labeled them “doomsayers.” The critics continue that today, ignoring that they were actually outlining what we need to do to avert catastrophe.

I tend to think this is just a debate tactic on the part of the critics, some of whom must be smart enough to know the Limits to Growth authors and others in the same vein have a solid argument. But those with vested interests in maintaining the status quo would like to discredit them. After all, many of them are making tremendous amounts of money doing business as usual. (think Exxon and their campaign to sew doubt about climate change)

I think you’re quite right that it’s going to take a change in worldview. I think that can come. It seems there are gradually more people speaking up. The question is whether it can happen fast enough. No matter what, though, any increase in the collective discussion of these issues will have a positive effect in the long run.
