In New York City, we seem to have adapted to the summer heat by people carrying these hand held fans everywhere. Asian style sun umbrellas also seem more popular.

Hope is that expansions to Orlando and Tampa stabilize profitability at current debt levels, or rates go down and ease up on financial conditions. But worst case scenario seems like there is a debt restructuring or bankruptcy which allows assets to survive in private form.

Brightline seems close to viable, and a big issue is the debt. 800k riders in Q1 of 2025 (11% increase); net loss down to $80m from $116m. Main challenge is $4.4b in existing debt. New $400m sale here for refi + expansion to Tampa.

New York has increased spending per pupil 67.5% from 1999-2000 to 2020-2021, yet test scores have dropped 0.4% over that period.
Both K-12 traditionalists and reformers should grapple with this data: the main "improvement strategy" has been to increase per pupil spending. You can examine the top of the chart to see how that worked out/1

And hookworm eradication!
Everyone credits AC, but here's another reason the south started booming only post-war: it was full of malaria for centuries. The issue was not seriously tackled until FDR established the Office of Malaria Control, which later became the CDC. They eliminated the disease in 1951.

Seems reasonable?.
Denmark has proposed a law to give citizens copyright to their faces, voices and likeness in a bid to curb unauthorized deep fakes. The law gives folks legal ground to go after anyone who uses their image to produce AI generated content without consent.

In a better world, the US would make up for its lack of HSR by putting in a super fast maglev system connecting major cities.
CGTN showcasing China's 600km/h maglev train. It runs on rubber wheels at lower speed. After reaching 150km/h, wheels are retracted and vehicle is suspended as it moves along.
