Great to see some momentum in the space. I looked into this about a year ago and concluded that I could *personally* pull off about $2 a tree if I really went at it just with commodity resources. Then based on looking at how things scaled in other domains guessed that you could get down to maybe $1 a tree with scaling + an effective org around you. That plus the idea that if smart people spent some serious time analysing cost bottlenecks harder costs would go down even more multiplied out by the relative carbon sequestration cost compared to next best geoengineering soltuions I concluded that this likely wouldn’t remain neglected for very long and stopped paying attention. I still think climate shifts are going to be terrible in lots of minor costly ways and we may still fail at the coordination needed to get it *right*, but I’ve mostly stopped paying attention to the doom and gloom estimates.
