I agree that we are facing the greatest crisis that humanity has ever faced, and we're sprinting towards that cliff.

I'm all for investing into large scale production of technology that pulls carbon gasses from the air. I just want to be sure this technology works as advertised and results in a net negative of atmospheric carbon. The last time we need to do is scale up something that doesn't work.

There's a lot we can do to mitigate the upcoming climate crisis, but most of the biggest impacts we can make (such as reducing carbon emissions) gas a lot of resistance. I'm not very optimistic that humanity as we know it will survive past this great filter.
