Huge miss that they didn't call this "Tip or Treat"
A Knicks fan recreated OG Anunoby’s classic tip-in in their front yard for Halloween 🔥

In a month's time, NYC went from
📈 having a summer for the history books
to
📉 having the plagues *from* the history books – at Manhattan, NY

“So often this city comes together because we are forced to, by a moment of tragedy or adversity, what a gift it is to be brought together by pure unfiltered joy.”
NYers are always at their best when things are at their worst — they rise to the occasion and reconnect with their community. Hell, one of my best city memories was the Aug'03 blackout.
This one's different. We get to bond over something really, really wonderful. LGK!! 🏀 – at Manhattan, NY
"It is different because New York’s mass unifying events tend to imply unbearable tragedy: 9/11, Sandy, Covid.
Maybe the disorientation of this championship run was that shared experiences in the city were allowed to be good, gleeful, uncomplicated." nytimes.com/2026/06/14/nyreg…

The biggest bullshit move by DHS in its history. So everyone on a O1 or H1B visa would have to stop working legally in the US, go back to their country and wait for years of backlog? This includes top scientists in our universities, founders of billion dollar companies (at least 3 just in our portfolio would be affected by the way). And if we look at individual countries it becomes even more bs. Indians would have to wait decades. Russians don’t have anywhere to go (there is no US embassy in Russia, hello?).
This is the worst imaginable way to disrupt important work for the country and pretend you’re fighting some loophole.
"As agents take on execution, humans direct work / own outcomes. Bottleneck: incentives + mgmt behavior. Only 13% of workers are rewarded for reinvention even if results are missed. That's how you get private productivity and public stagnation." @hnshah

⚡️The deeper signal is youth risk did not disappear.
It migrated inward.
Teen drinking fell because the old physical world of adolescence got dismantled. Alcohol belonged to a social ecosystem: unsupervised time, cars, parties, local jobs, malls, basements, boredom, flirting, older siblings, house gatherings, and the chaotic peer world where teenagers learned who they were by colliding with other people in real space.
That ecosystem was replaced by phones, surveillance, parental tracking, algorithmic entertainment, social anxiety, online status games, and a much thinner physical commons.
So the surface looks healthier. Fewer kids drinking. Fewer kids using weed. Fewer kids doing reckless things in public.
The hidden layer looks worse. The young are less reckless because they are less socially embodied. Less initiation. Less unsupervised friction. Less courage-building. Less embarrassment and recovery. Less real dating. Less independence. Less contact with the physical world before adulthood demands it.
The old teenage world produced damage, stupidity, alcohol abuse, pregnancy risk, fights, accidents, and bad decisions. No need to romanticize it. But it also produced social reps. It forced young people through discomfort. It made them practice attraction, rejection, conflict, reputation, risk, repair, and status in the open.
The new world suppresses visible risk while increasing invisible fragility.
That is the trade.
A teenager can avoid drinking, avoid parties, avoid sex, avoid driving, avoid real confrontation, avoid rejection, avoid shame, avoid danger, and still arrive at 23 emotionally underbuilt. Cleaner behavior does not automatically mean stronger formation.
This is why the marriage chart and the teen drinking chart are the same story at different stages. People are not suddenly failing to pair in adulthood. The whole pathway into embodied adulthood has been slowing for years before marriage even becomes the question.
The real truth: society solved part of the teen vice problem by shrinking the arena where teenagers become adults.
It took away the dangerous commons and replaced it with controlled isolation.
The result is safer kids with weaker initiation into real life.
