🚨 University professors have been saying AI is completely destroying learning and that we'll soon have an AI-powered, semi-illiterate workforce. Here's a glimpse into the educational apocalypse: "Sarah, a freshman at Wilfrid Laurier University in Ontario, said she first used ChatGPT to cheat during the spring semester of her final year of high school. (...) After getting acquainted with the chatbot, Sarah used it for all her classes: Indigenous studies, law, English, and a “hippie farming class” called Green Industries. “My grades were amazing,” she said. “It changed my life.” Sarah continued to use AI when she started college this past fall. Why wouldn’t she? Rarely did she sit in class and not see other students’ laptops open to ChatGPT. Toward the end of the semester, she began to think she might be dependent on the website. She already considered herself addicted to TikTok, Instagram, Snapchat, and Reddit, where she writes under the username maybeimnotsmart. “I spend so much time on TikTok,” she said. “Hours and hours, until my eyes start hurting, which makes it hard to plan and do my schoolwork. With ChatGPT, I can write an essay in two hours that normally takes 12.” - "By November, Williams estimated that at least half of his students were using AI to write their papers. Attempts at accountability were pointless. Williams had no faith in AI detectors, and the professor teaching the class instructed him not to fail individual papers, even the clearly AI-smoothed ones. “Every time I brought it up with the professor, I got the sense he was underestimating the power of ChatGPT, and the departmental stance was, ‘Well, it’s a slippery slope, and we can’t really prove they’re using AI,’” Williams said. “I was told to grade based on what the essay would’ve gotten if it were a ‘true attempt at a paper.’ So I was grading people on their ability to use ChatGPT.” - AI in education is a serious topic, and many schools and universities are blindly jumping into the "AI-first" wave without considering short and long-term consequences. It would be great to hear more from teachers and educators to understand potential solutions. This might be a great opportunity for rethinking the education system and how students are assessed. - 👉 Link to the full article below. 👉 To learn more about AI's legal and ethical challenges, join my newsletter's 94,700+ subscribers (link below).

Texas just passed California in utility-scale solar. And it's not close in wind or energy storage.











I've been waiting for a map like this and would love to see it for more places: These are EV charging price by US state translated into gasoline prices so you get a like for like comparison of driving costs. Source: reddit.com/r/dataisbeauti…




Anthropic CEO Dario Amodei: “50% of all tech jobs, entry-level lawyers, consultants, and finance professionals will be completely wiped out within 1–5 years.”




There is no energy transition to renewables "Rather than replacing fossil fuels, renewables are adding to the overall energy mix" Energy Institute Statistical Review 2025 energyinst.org/statistical-re… energyinst.org/exploring-ener…

The use of primary energy on the vertical axis is an old trick by the fossil fuel industry to mislead people into thinking that one unit of fossils = one unit of renewables. In fact, one unit of primary energy for wind or solar electricity is the equivalent of three units of fossil fuels for electricity. Another trick is to pretend we need all those fossils if we switched to renewables. In fact, if we switch to renewables, 12% of the fossil fuel energy disappears because that is how much energy is used to mine-transport-refine fossil fuels+uranium for energy, and we wouldn't need to do that anymore A third trick is to pretend we need so much energy if we go to all electricity powered by renewables. In that case, because EVs use 75% less energy than gasoline/diesel vehicles, heat pumps use 75% less energy than combustion heating, etc., energy demand goes down another 42%. In sum, this plot illustrates the real story of where we are and where we need to go. The proper metric is end-use energy, not primary energy. web.stanford.edu/group/efmh/jac… and here's the paper web.stanford.edu/group/efmh/jac…
