I don’t think its arrogance just a reflection of the current level of understanding earth systems. We have grown in capacity and reach to be affecting the fundamental systems of life. Those systems have been self-healing but we are causing unprecedented significant and wide reaching change and there’s a non-zero chance we will hit positive feedback loops that completely disrupt the mechanisms of life on this planet.

Its a very minor point of disagreement but its just to acknowledge the scale of impact we are making. We’ve been fooled by how good earth is maintaining life that its less fragile and precious than it is
