It changed because of the mayor and because of our taxes. This stuff makes me really happy to be a taxpayer.

By that measure Twitter peaked in 2012. It took 9 years and an acquisition by a comically awful person for Bluesky to even *begin* to nip at its toes.

Ok yes and also lol. I imagine they deliberately cap the RTs per account but maybe not.

Got into an argument with a guy in a WhatsApp group for my friend’s wedding and he came out with this absolute banger. I thought it had to be a copypasta, but no!
Screenshot that reads: “the errors in your thinking and language are so numerous and replete, i am afraid further discussion would only lead to your further perpetuating misrepresentations and continually remaining insensate to basic perception of and correct construal of empirical evidence. this would not be a constructive use of my time. good luck to you.”

Toronto is an extremely violent city. I just witnessed this guy beat up three guys and nobody around him did ANYTHING. People seemed numb to it. And then he did it AGAIN.

DeBlasio had lots of connections in NY politics from more than a decade of experience in New York politics. AOC is a better comparison — her incumbent opponent was endorsed by the party establishment (including DeBlasio)
Screenshot of a Wikipedia article about the 2018 New York's 14th congressional district election, which reads: Governor Cuomo endorsed Crowley, as did both of New York's U.S. Senators, Chuck Schumer and Kirsten Gillibrand, as well as New York City Mayor Bill de Blasio, 11 U.S. Representatives, 31 local elected officials, 31 trade unions, and groups such as the Sierra Club, Planned Parenthood, the Working Families Party, NARAL Pro-Choice America, Moms Demand Action for Gun Sense in America, and others.

v good blog
Screenshot of an article that reads, in part, "There is very little that aggravates me more than watching people who are either evil or stupid poorly manipulate holy texts for their own gain. I was raised in the evangelical church in Texas. My father is a minister. I have read the Bible more than probably any other book I will ever read. And I have watched, for my entire life, people who want power and glory for themselves rip out the pages and make origami swans with them in order to get the words to line up just how they want them to be, so they can justify their own actions."

Here Lionel Bently suggests that AI training is *probably* legal under copyright law — but the outputs are likely not copyrightable. Definitely does not seem to be an open-and-shut thing among legal scholars.
Screenshot of a podcast transcript that reads, in part: And at one level, to train an Al system, you have to make some temporary reproductions of the work, but you're doing it in a different way, probably, than most reproductions, because the reproductions are not really for the expressive form of the work. They're being made so that the Al system can analyze the work and generate connections between different aspects of the work.

If you're gonna allege AI usage, at a minimum you have to show that AI can produce something similar. Spoiler: it can't!

He‘s not saying that engineers will be 10x more efficient (though that’s what a lot of people, including this article, heard). And also yes 90% is an absurd number (I use Claude and it’s great but still has so far to go)
I do have a fair amount of concern about this. On one hand, I think comparative advantage is a very powerful tool. If I look at coding, programming, which is one area where Al is making the most progress, what we are finding is we are not far from the world—I think we'll be there in three to six months-where Al is writing 90 percent of the code. And then in twelve months, we may be in a world where Al is writing essentially all of the code. But the programmer still needs to specify, you know, what are-what are the conditions of what you're doing, what-you know, what is the overall app you're trying to make, what's the overall design decision? How do we collaborate with other code that's been written?
