When the oil wells in Kuwait were set on fire as the Iraqis left, the prediction was that it would burn for years and be a global environmental catastrophe. When crack teams from around the world converged on Kuwait, invented new techniques on the spot and put the fires out in a mere six months, that did not get anywhere near the hype that the initial dire predictions got.
In the 1990's, they were predicting a global financial meltdown due to y2k and people were prepping for it -- putting away food stocks, etc. That got quietly solved and no one wakes up every day going "THANK GOD THEY SOLVED THAT AND WE AREN"T LIVING IN THE POST Y2K APOCALYPSE!!!!"
I think we can solve this. I also think if we do solve it, people will act like the fears we are expressing now about it were overblown. People are terrible about being unable to count the disasters that did not happen. When things go well, we seem to think that is "normal" even though it really is not.
I am aware we may not solve it and the world may, in fact, go to hell the way everyone is predicting. But may not and cannot are different things. But, you know, we are all dust in the wind anyway. In another million years, none of this really matters.
My experience is that if you have something positive to say, people pretty much ignore you. I am still trying to figure out how to get traction for being able to talk about things that actually work in various problem spaces. People mostly do not want to hear it. They are far more interested in being all emo about the state of the world while carrying on with their lifestyle as usual for the most part.
