Wow this is a shockingly poor driving performance. We're not very close to autonomous driving, friends

Tesla's robotaxis crash at 10x the rate of human drivers.

Last month, Tesla confirmed the fleet had traveled roughly 250K miles. With 7 reported crashes at the time, Tesla’s Robotaxi was crashing roughly once every 40K miles.

The average human driver in the US crashes about once every 500K miles.

Tesla reports another Robotaxi crash, even with supervisor as it moves to remove them

Tesla has reported yet another crash involving its Robotaxi fleet in Austin to the NHTSA. The new data keeps the...

So epstein was a mentor to summers in abusing young women. In 2018.

Marshall Steinbaum @econmarshall.bsky.social · Nov 15

The emails have Summers reporting to Epstein about his attempts to date a Harvard economics student & to hit on her during a seminar she was giving.

It actually matters what you teach!

This absolutely nuts.
I'm not sure there is a single scientist in the US who has not advised a Chinese graduate student in the past 5 years.

Roland Hatzenpichler @environmicrobio.bsky.social · Nov 14

“The prohibited activities would include joint research, co-authorship on papers, and advising a foreign graduate student or postdoctoral fellow. The language is retroactive, meaning any interactions during the previous 5 years could make a scientist ineligible for future federal funding.”

U.S. Congress considers sweeping ban on Chinese collaborations

Researchers speak out against proposal that would bar funding for U.S. scientists working with Chinese partners or training Chinese students

Whoa! According to Jason Furman the only US industry to grow this year has been data centers & IT

David Ho @davidho.bsky.social · Nov 10

This seems significant.

"U.S. GDP growth in the first half of 2025 was almost entirely driven by investment in data centers and information processing technology, according to Harvard economist Jason Furman."

Without data centers, GDP growth was 0.1% in the first half of 2025, Harvard economist says | Fortune

Is a U.S. without data centers a country without GDP growth?

Ok. Do you have a source that explains why it won't happen? I'm not a technical expert but am curious.

And develop cheap green hydrogen.

Electrification could now reach 75% of all energy demand, as the road-transport and heating sectors rapidly electrify 🔥🚗

These two sectors account for 50% of global energy use and are now ready to switch from fossil molecules to clean electrons.

Cornell's agreement actually explicitly restored academic freedom but it allows gov access to anonymized admission data (but not set the criteria).

Now would be a great time to stop legacy admission practices across the ivies and other top private universities.
