One time I mentioned to my boss how I think humanity is doomed to destroy life on Earth because we never learn from our mistakes until it's too late.
My boss said that she is optimistic that we'll get climate change under control because of her young daughter's generation. I immediately backpedaled and agreed that we'll probably figure it out and technology will save us, but I was just lying to both of us feel better.
Of course we need to keep trying to solve these climate issues, but a lot of people are in denial about how bad things already are and underestimate the kind of societal shifts that need to happen right now because of the cognitive dissidence many of us hold, even scientists.
