[ad_1] This as-told-to essay is based on conversations with Adam Pretorius, who’s been a real estate agent in Iowa since 2009. Pretorius was targeted as part of a vacant land scam in which scammers impersonate property owners and solicit agents to fraudulently sell their land. The conversation has been edited for length and clarity.I’ve been practicing real estate since 2009. I focus just on residential, and as a top performer in town, maybe I got complacent.I’d heard of scammers being out there, but not specifically on land or listings. Maybe it was my own complacent belief that it wasn’t going…

[ad_1] Deborah has fast become one of Nicole Ramirez’s favorite colleagues. She’s quick to deliver compliments, sharp-witted, and hyper-efficient. Perhaps best of all, there’s no internal competition with Deborah at the health marketing agency they work for, because she isn’t on the payroll. She isn’t even human.Ramirez, a 34-year-old who lives in the Pittsburgh area, says she randomly chose the name Deborah as a way to refer to the generative AI app ChatGPT, which she began using about a year ago to help her with basic tasks like drafting emails. As time went on, she asked Deborah to do more…

[ad_1] The second half of the year is looking grim for millions of student-loan borrowers.That’s not necessarily a surprise — President Donald Trump’s Department of Education restarted collections on defaulted student loans in May after a five-year pause, meaning borrowers are once again subject to negative credit reporting and the withholding of federal benefits, like wages.The New York Federal Reserve’s quarterly report on household debt and credit showed how stark the surge in delinquencies for student-loan borrowers is — it found that 10.2% of student borrowing was serious delinquency in the second quarter, which is more than 90 days past…

[ad_1] Everybody wants to be Ryan Reynolds. Donald Trump wants to be Ryan Reynolds. The “SmartLess” podcast guys want to be Ryan Reynolds. Even Klarna wants to be Ryan Reynolds. I don’t mean they want to star in “Deadpool” or marry Blake Lively (though neither of those is a bad deal). I mean that they’re all slapping their brands on mobile phone networks in an attempt to make a little extra bank.If you’re familiar with Mint Mobile, a mobile phone network that offers inexpensive prepaid plans, it’s probably because you’ve seen Reynolds in an ad for it. The actor-turned-entrepreneur bought…

[ad_1] xAI CEO Elon Musk paid a rare compliment to his rival Google on Wednesday.”Outside of real-world AI, Google has the biggest compute (and data) advantage for now, so currently has the highest probability of being the leader,” Musk wrote in an X post.But that “may change in a few years,” he added.”For the foreseeable future, the major AI companies will continue to prosper, as will xAI. There is just so much to do!” Musk wrote.Musk and Google did not respond to requests for comment from Business Insider.Google has long been a mainstay in AI.In 2017, Google Research released a…

[ad_1] In January 2020 Nick Moakes, chief investment officer of the Wellcome Trust, noticed a sharp difference between the muted response of the stock market to the emergent coronavirus and the charitable foundation’s own prognosis. Moakes’s colleague Sir Jeremy Farrar, a world-leading epidemiologist and then the director of Wellcome, the UK’s largest provider of non-governmental funding for scientific research, was one of the earliest to warn of the virus’s significance.“We thought this is really odd, because markets are doing nothing, and yet we’re being given a bunch of signals here, which tell you that the markets are way too complacent,” Moakes,…

[ad_1] All hail the new ChatGPT, which is much better than the old ChatGPT, which we’re getting rid of.That was the messaging from OpenAI CEO Sam Altman and his team last week.A day later, Altman changed his mind. He told the world the older version of ChatGPT was going to stick around, after all — in addition to the new version that was meant to replace it.I’m not getting into the weeds here about the change and change back, which is confusing for people who use ChatGPT, and impenetrable to non-users. (If you want to, I suggest you head to…
