The scariest finding in this paper: the subjects couldn't tell it was happening.
UPenn ran this study on 48 healthy adults. One group slept 8 hours. Another slept 6. Another slept 4. For 14 straight days. They tested cognitive performance every 2 hours from 7:30am to 11:30pm.
The 6-hour group's reaction times, working memory, and sustained attention deteriorated on a near-linear curve. By day 14 they were performing at the same level as someone who hadn't slept at all in 48 hours. The 4-hour group hit that threshold by day 6.
Here's the part that should unsettle everyone who thinks they "do fine" on 6 hours: the subjects' self-reported sleepiness flatlined after the first few days. Their brains kept getting worse. Their perception of how impaired they were stopped updating. The cognitive decline was invisible to the person experiencing it.
The researchers found a hard threshold. Any wakefulness beyond 15.84 hours in a day produces cumulative neurobiological cost. That cost compounds every single day you exceed it and does not reset with a weekend of sleeping in.
About 35% of American adults sleep less than 7 hours a night. 40% of those get 6 hours or less. In 1942 that number was 11%. We built an entire professional culture around a sleep schedule that this paper says is functionally equivalent to pulling consecutive all-nighters.
"I'm fine on 6 hours" is the most common response to sleep research. The first thing chronic sleep debt destroys is your ability to notice chronic sleep debt.

Sleeping <6h a night for 2 weeks reduces cognitive performance equal to 2 nights of total sleep deprivation.

My latest, for @TIME: Why Dubai Will Abide
NB: If you’d told me 25 years ago I’d someday describe Dubai as one of the world’s great cities, I’d have laughed you out of the room.
But here I am.

Half of US data centers planned for 2026 are expected to be delayed or canceled. One big reason is shortage of electrical equipment, such as transformers, switchgear and batteries. US doesn't have manufacturing capacity, forcing it to rely on imports. 🎁🔗 bloomberg.com/news/features/…

While social media is polarising, evidence suggests AI may nudge people towards the centre.
This holds true of all studied models. Grok is more right-leaning than other models, but also has depolarising effects.

@rajeshsawhney Singapore, KL, Hong Kong Doha and Riyadh should be in an expansion drive after that, eventually an ACC super league, a la UEFA Champions League?
