NEW | California just reached a world-first solar milestone
Over HALF (51%) of electricity generation across the whole month of May came from solar power.

I wonder, if you polled people, how much extra they would pay each year to have their city *not* be covered in thick, choking wildfire smoke for days at a time. I wonder if that might give you more insight into "willingness to pay" vis a vis climate change than asking in the abstract.

I keep hearing folks talk about the loss of flow state with agentic coding, and as a long time exec agentic coding is the highest flow state activity I’ve done in a decade+.

Spent the weekend in the Bay Area talking with 100+ technologists, and thinkers about AI — and my takeaway is the primary challenge, limitations and existential risk in the tech is that folks are accepting the ways in its accelerating wealth inequality.
