?Shoddy Teslas

"Tesla blamed drivers for failures of parts it long knew were defective".
Update: I have received numerous responses from Tesla supporters questioning the reliability of those two articles.   If you're in the market for a Tesla, you should do your own consumer research.  (I don't own a Tesla, and was not interested in purchasing one even before prior those recent articles.)

Criminals Complaining To Federal Regulators

"Ransomware gang files SEC complaint over victim's undisclosed breach":

The ALPHV/BlackCat ransomware operation has taken extortion to a new level by filing a U.S. Securities and Exchange Commission complaint against one of their alleged victims for not complying with the four-day rule to disclose a cyberattack.

(Presumably, this puts more pressure on the victim to pay up.)

AI Legislation

"Brazilian city enacts an ordinance that was secretly written by ChatGPT"

“If I had revealed it before, the proposal certainly wouldn't even have been taken to a vote,” [city councilman Ramiro] Rosário told the AP by phone on Thursday. The 36-member council approved it unanimously and the ordinance went into effect on Nov. 23.

“It would be unfair to the population to run the risk of the project not being approved simply because it was written by artificial intelligence,” he added...

Keeping the proposal's origin secret was intentional. Rosário told the AP his objective was not just to resolve a local issue, but also to spark a debate. He said he entered a 49-word prompt into ChatGPT and it returned the full draft proposal within seconds, including justifications.
