ChatGPT and other artificial intelligence (A.I.) programs have become more and more present as companies invest in them. However, much of the promotion has gotten to the point that advertising A.I. features in products could be considered a turn-off with consumers. Many companies have already replaced human writers with ChatGPT, but there is one person that proves that ChatGPT cannot be relied on for the written word: Donald Trump.

While obviously a controversial figure that supports A.I., a recent study of Trump’s speeches is showing how large language models (LLMs) like ChatGPT fall short. Researchers from the College of International Studies, National University of Defense Technology in China chose Trump’s Republican nomination acceptance speech after he survived his assassination attempt, his post-election victory speech, his 2025 inaugural address, and his speech to Congress to test ChatGPT-4’s abilities. They chose those speeches because they were specifically filled with emotionally charged language that often used metaphors to frame political topics. They tasked ChatGPT-4 to analyze the 28,000 word total of the speeches and see if it could understand the context of the speech, identify potential metaphors, categorize them by theme, and explain their likely emotional or ideological impact.

The results showed that while ChatGPT is impressive, it still couldn’t fully grasp certain aspects of human language such as metaphors. While it was able to recognize some overly used metaphors, it still struggled to properly identify or explain the context/meaning of others. In some instances, it would incorrectly classify something as a metaphor such as Israel’s Iron Dome missile defense system, which technically is a proper noun. Forbes even recognizes metaphors as something LLMs like ChatGPT cannot grasp. While ChatGPT understands information, humans can tell and understand stories and parables.

In its defense, ChatGPT over time could become more sophisticated and learn how to properly classify and use metaphors, similes, idioms, rhetorical questions, and persuasive asides effectively. However, that doesn’t appear to be happening any time soon and as language evolves it will be in a constant state of catching up. LLMs can certainly detect patterns in speech, but it lacks nuance and the ability to understand context. At this point, it is an enhanced version of the predictive text that you regularly use on your phone and shouldn’t be used as more than a tool rather than a replacement.

Metaphors aren’t the only drawback for LLMs. When it comes to idioms, generative LLMs like Google A.I. will take made-up ones that don’t exist such as “you can’t lick a badger twice” and “a loose dog won’t surf” and make up meanings behind them rather than cite them as original nonsense. College students who use ChatGPT to write papers for them are getting caught by professors as the A.I.-generated term papers lack engaging and persuasive language.

Human writing isn’t just more efficient than ChatGPT, but it’s also more economically sound. Aside from companies ending up rehiring human writers to correct mistakes made by A.I. and to create more persuasive marketing as consumers become more savvy to A.I.-generated content, there is also still a lot of legal red tape regarding copyright infringement and “who owns what” when a company uses A.I. to create something. Since generative A.I. derives from original works whenever it creates something based on a prompt, the jury is literally still out on if the prompt writer owes something to the artists the A.I. is drawing from.

Continuing with economics, A.I. isn’t very cost efficient at this time. Generating work through A.I. requires a significant amount of electricity to both create the prompt that it was given .Training ChatGPT-3 alone required enough electricity to power 130 American homes for one year. Each day, A.I. data centers consume the same amount of water as 4,200 Americans. While there could be experimentation into finding more energy-efficient ways for A.I. to work, the rush to make A.I. profitable for investors is taking higher priority rather than making it less impactful on consumers, the environment, and our power grid.

At this point, ChatGPT and A.I. isn’t living up to the promise that many of its champions proclaim, however if it can provide great opportunities if it is treated with nuance and time with an understanding human hand. However, if it cannot accurately 100% decipher what our leaders say, it probably shouldn’t be used as a replacement for any work that humans can and should do.

  • How D.C.’s ‘humanure’ fertilizer creates lush gardens and big profits while improving the environment

    The District of Columbia Water and Sewer Authority—now known as D.C. Water—has long provided water and sewer services to Washington, D.C. But for the past decade, the utility has also had an unexpected side hustle: turning human wastewater into fertilizer with flourishing results.

    At most wastewater treatment plants, flushed water is cleaned, while the remaining solid matter is hauled away for disposal. Over time, transporting and disposing of that waste can cost millions of dollars while increasing carbon emissions from the trucks carrying it. A decade ago, however, D.C. Water decided to invest in transforming the solid waste into “humanure” rather than throwing it away.

    Growin’ grass and makin’ gas

    At the end of the wastewater treatment process, the collected human waste solids are processed into biosolid fertilizer using technology developed by Norwegian company Cambi. The process doesn’t just produce high-quality fertilizer—it also generates biogas that can be put to good use.

    “So you get up to 40% more biogas,” Cambi CEO Eirik Fadnes said. “That biogas can be used to generate electricity to be used elsewhere in the wastewater-treatment plant or put on the grid and sold.”

    D.C. Water sells the biosolid fertilizer under the brand name Bloom, and it’s already proving to be a success. Bloom has been used throughout the Washington, D.C., area by customers including Catholic University, Mount Olivet Cemetery, and the Franciscan Monastery. It’s also used on numerous lawns, school grounds, community gardens, and golf courses.

    Success by the numbers

    The numbers underscore D.C. Water’s success. To date, nearly 400,000 tons of Bloom have been sold across Washington, D.C., Maryland, Pennsylvania, and Virginia, generating $13.6 million in revenue. D.C. Water originally estimated it would take 20 years for Bloom to pay off its investment. But thanks to strong demand from institutions, landscapers, and local garden centers, the utility is now on pace to recoup that investment in just 12 years.

    Bloom is also helping D.C. Water meet its environmental goals. By turning waste into a useful product instead of hauling it away for disposal, the utility has reduced its carbon footprint by roughly 50,000 metric tons of CO₂ emissions each year—the equivalent of taking more than 11,700 gas-powered cars off the road annually. The process also produces biogas, which can be converted into electricity to help offset the energy costs of wastewater treatment.

    Human waste works wonders

    None of this would matter if human biosolids weren’t effective at improving soil. “Humanure,” a term coined by Joseph Jenkins, refers to compost made from properly treated human waste. Because human feces can contain disease-causing pathogens, it must be handled carefully. After all, we call it “waste” for a reason.

    When human waste is composted correctly, naturally occurring microbes break down the organic material while generating enough heat to destroy harmful pathogens. Over time, the result is a nutrient-rich compost that can improve soil health. Some farmers even build specialized outdoor composting toilets to create humanure for use on their land.

    Should D.C. Water continue on this path of simultaneous profitability and environmental improvement, it’s likely other wastewater treatment plants will follow its lead.

  • A Spanish park has been free of wildfires for over a decade thanks to 18 donkeys

    According to NASA, wildfires have doubled worldwide due to climate change. Throughout the globe, governments and environmentalists have been trying to find ways to curb the fires. One particular national park in Spain has found a solution that has been keeping them fire-free for over a decade: donkeys.

    Since 2014, the Firefighting Donkey Battalion unit consisting of 18 donkeys has been preventing wildfires in Doñana National Park in Doñana, Spain. The mission these donkeys do is simple: eat the dry brush that usually sparks and fuels wildfires. The donkeys spend up to seven hours a day using their voracious appetites to graze and clear a 130 by 50 feet area of dried grass, scrub, and other vegetation.

    Why donkeys?

    While humans can do this type of clearing out of dry brush, using donkeys for this work is arguably more effective. While it is a slower process, it is consistent and thorough. Donkeys are able to quietly patrol in areas that are inaccessible to vehicles. In exchange for the feasting, the donkeys get about eight gallons of water and rest. No money or fuel needed.

    The donkeys’ bodies are also pretty much built for this kind of environmental work, too. Their stomachs are built to eat the same rough and dry grass repeatedly without issues. These daily grazings slowly but surely remove potential origin sources for fires. As a bonus, the donkeys are naturally disposing of the dried vegetation whereas humans would have to find a different way to dispose of it.

    Having donkeys or other livestock graze in such areas was once more common in agriculture prior to modern farming. Some argue that the machinization of farming and urbanization have reduced the number of grazing animals. This in turn allows more vegetation growth that become dry spots for more wildfires to occur.

    The method expands

    This method has been so successful that other areas of Spain have adopted it. In 2020, Tivissa launched the Burros Bomberos project with three donkeys to so much success they’ve expanded. They now have 40 donkeys grazing and clearing nearly 400 hectares of land.

    The Andrea Association in Allariz uses a team of donkeys to clear and maintain nearly 1,000 hectares of a biosphere reserve. Using GPS to monitor the donkeys’ activity, the group of grazers travel 19 kilometers per day to feed. Similar initiatives have since started in Basque Country, Catalonia, and Galicia, too.

    Other ways to combat wildfires

    In the United States, California has been using goats in a similar function. The group Fire Grazers Inc. has been contacted throughout California to bring hundreds of goats to eat dried vegetation. Much like donkeys, goats are built to eat rough and dry brush. This includes certain plants such as star thistle that are painful for human hands to grab.

    It’s important to note that donkeys or other animals that eat dry scrub are the primary solution to wildfires. The same folks behind these initiatives also advocate proper forest planning and land management. This includes reducing the amount of easily flammable species of plants and trees such as pine. It takes thought, care, work, and maybe a bunch of donkeys to make a difference.

    Spanish zoo study suggests that giraffes can do basic math

    These hoofed mammals can understand addition.

    The results of an experiment done in a Barcelona zoo suggest that giraffes are capable of doing basic mathematics.

    A group of researchers from the University of Leipzig, the Max Planck Institute for Evolutionary Anthropology, and the University of Barcelona published their study observing four giraffes at the Barcelona Zoo. The experiment involved the giraffes observing containers that had different amounts of carrot pieces inside.

    How did this experiment work?

    The researchers showed each giraffe the two yellow containers and the amount of carrots within each one. After a few seconds, they closed the containers, keeping the carrots out of sight. They then showed each giraffe a green container which had extra carrots inside. Researchers took the carrot pieces from the green container and placed them into one of the closed yellow containers. They then let each giraffe independently choose which of the two closed yellow containers they preferred, without them seeing the total number of carrot pieces within each box.

    The results found the giraffes would choose the container that had the most carrot pieces around 68% of the time. This suggests to the scientists that the giraffes were mentally adding the carrots up in each container before making their choice. After all, there have been past studies suggesting that other hoofed mammals, such as horses, had similar capability of basic quantity tracking.

    The researchers did the experiment again. Only this time they subtracted the amount of carrots in each container. The giraffes were mostly unsuccessful at finding the container with the most pieces. So while giraffes showed signs of knowing addition, they don’t quite process all forms of arithmetic.

    Math = Survival

    Scientists believe that this understanding of addition helped giraffes survive in the wild. They cite that acacia trees, a dietary staple for wild giraffes, can be spread far apart in Africa. Being able to figure out which area has the most trees and the most leaves can help them decide where to graze next.

    Giraffes also live in flexible groups that often change in size. One grouping can mix in with another group and then branch off or away. This means that the giraffes often have to keep track of those currently within their group and surroundings to survive.

    Can other animals do math?

    Giraffes are just the latest animal species known to have some form of mathematical skill. Chimpanzees displayed similar abilities to count as giraffes in a similar experiment that involved them picking the bowl with the most chocolate pieces rather than carrots. Chickens and black bears also showed aptitude in quantity tracking, too. 

    Scientists theorize that most of the animals that can do this basic math through evolutionary survival. After all, the animal that can deduce where more food is tends to live longer.

    One species that displays remarkable mathematical ability are Tunisian desert ants. An observation of their navigational skills of finding their way to food and back to their nest suggests they use the sun as a compass in combination with mentally keeping track of the number of steps they take in a three-dimensional space. In short, these desert ants possess basic geometric and trigonometry skills.

    While you wouldn’t want wild animals to calculate your taxes, it’s interesting to see how rudimentary math is a language that goes beyond species.
