The Treeline is a clear view of AI’s transformation of work (and adjacent things), written for people who need to see what’s happening.
Below treeline is normal social media — a forest of hot takes, panic performance, and churn. You can’t see more than a few feet.
The Treeline is the altitude where the noise thins and the view opens up. I spend a lot of time in the forest, reading widely, curating with judgment from careers in intelligence and tech, then bring back what’s worth knowing.
More about me
The em dashes are mine, but I do use AI to help with writing, organizing, and workflow.
I don’t believe safety is the highest virtue, nor that risk should always be avoided. I believe in acting in the face of risk because action creates signal.
