“OPENAI, through its AI chatbot program ChatGPT, provides legal advice, legal analysis, legal research and can draft legal documents and papers for submission to a Court. ChatGPT provides these legal services to any user who requests them. ChatGPT is not licensed to practice law in Illinois.” They're asking for declaratory judgement that OpenAI has been practicing law without a license, a permanent injunction barring them from providing the disgruntled woman with any more legal assistance, $300,000 to reimburse their costs in responding to the bogus motions, and $10 million in punitive damages.

A woman sues her insurance company for terminating her disability benefits. They reach a settlement and agree that the suit will be dismissed with prejudice.

She decides she doesn't like the settlement and asks her lawyers to reopen the case.They say they can't: it was dismissed, and in the settlement she agreed not to reopen the case.

She asks ChatGPT if her attorneys are lying to her. It says they are. She fires them and continues pro se, advised by ChatGPT.

CharGPT generates legal arguments for reopening the case, which she files, and 21 more motions, a subpoena, and eight other notices and statements, which she files.

The court denies her motion to reopen the case.

Advised by ChatGPT, she files a new suit against the insurance company and submits 44 more motions, memoranda, etc., which include citations to nonexistent cases.

Now the insurance company has sued OpenAI for tortious interference with their settlement contract.

“Breakfast is a vector space. You can place pancakes, crepes, and scrambled eggs on a simplex where the variables are the ratios between milk, eggs, and flour. We have explored too little of this manifold. More breakfasts can exist than we have known.”

This might be the most obsessively nerdy thing I've ever seen. One of the bronze ‘H’es in a sign was installed upside down, and the author dove into historical research to find out when and why.

“Most electronic shopping cart wheels listen for a 7.8 kHz signal from an underground wire to know when to lock and unlock. A management remote can send a different signal at 7.8 kHz to the wheel to unlock it. Since 7.8 kHz is in the audio range, you can use the parasitic EMF from your phone's speaker to ‘transmit’ a similar code by playing a crafted audio file.”

This sounds improbable but I needed to use it just now and it worked both times.

I think many people misunderstand the purpose of code review. The purpose of code review is not for the reviewer to find bugs, and certainly not for them to ensure that the code is bug-free. Anyone who depends on code review to find bugs is living in a fool's paradise. As everyone should know by now, it is not in general possible to find bugs by examining the code.

The primary purpose of code review is to find code that will be _hard to maintain_. The reviewer looks at the code and tries to understand what it is doing and how. If they can't, that means it will be hard to maintain in the future, and should be fixed now, while the original author is still familiar with it.
