can't take "LLMs are people" discourse seriously when we haven't even convinced everyone that all people are people.

🌡️ DC just shattered a century-old heat record. Wednesday's 90F was the latest such reading in recorded history, beating the previous mark by three days. It's no fluke. DC's mounting heat records tell the story of our warming climate. See the staggering list: www.capitalweather.com/dcs-remarkab...

One of my former students just witnessed this on Orange Line in the DC Metro - ICE/HSI abducting someone from the platform of Stadium-Armory. She was scared. She didn’t know what to do. She shouted “ICE is here!” to warn others. I’m proud she did that. And she bore witness.

I think it's closer to the truth that LLMs *can* save time on *some tasks* which can be valuable *if* you monitor them and check their output. But that doesn't get you a trillion dollars so they have to squint into the middle distance and say stupid sci fi bullshit instead

“Maybe this will fix me,” he thought as he completed the purchase for the LEGO “Rocking Plants” building kit
The completed LEGO “Rocking Plants” set, which features a pale green pot with a cartoon face, its tongue sticking out, and some small bright pink flowers; and a pale pink pot with a cartoon face, its eyes closed in elation, and a tall-stemmed flower with yellow and red buds. The flower pots seem to be friends!

There are already articles circulating trying to rewrite history and say America was great after 9/11 and united and thoughtful and just a reminder that that period was marked by intense and insanely racist hatred, paranoia, and a frothing desire for unhinged violence and oppression.

My favorite story is that she anonymously gifted high school band and music programs across the South, especially majority Black schools, with music, uniforms and instruments. We are all made better for living in the era of Dolly Rebecca Parton. May her memory be for a blessing always.

I'm not the first person to say this, but the bike industry in the U.S. is really missing a huge opportunity by not aggressively defending and promoting e-bikes. I think this is largely the result of it being an industry built on recreational cycling and not transit riding.

Ha ha I hate it here
From the New York Times:

It is a chaotic scene on the National Mall.
Several hundred people have refused to leave despite an order to evacuate because of severe inclement weather that is approaching. Some are even arguing with Secret Service agents. At one point, a crowd of people began running back toward the stage. An officer is sternly repeating the order over a bullhorn and the crowd is booing. Many have begun chanting "U.S.A., U.S.A." A federal law enforcement officer is trying to assure people that the event has not been canceled. Many are not convinced.
One man walking by blamed the situation on "liberals in the weather service," adding,
"I think this is baloney."
