Data from exoplanet research points to a "rare earth" conclusion
Yes, it would be accurate to make such a statement. Observations of exoplanets have indeed shown that planetary systems exhibit a remarkable diversity, much greater than what was anticipated based on our Solar System alone. Many exoplanets discovered do not fit into the neat categories previously envisaged from our Solar System's structure. For instance, the discovery of "hot Jupiters" (gas giants that orbit very close to their stars) and "super Earths" (rocky planets larger than Earth but smaller than Neptune) challenged our conventional understanding of planetary system formation.
These findings imply that systems similar to our Solar System might be less common than once thought. When it comes to Earth-like planets, while many have been found in the habitable zone (where conditions could potentially allow liquid water to exist), the additional conditions necessary for Earth-like life—such as significant liquid water oceans, plate tectonics, and a stable climate system—are not easily inferred from distance observations alone. These factors contribute to the complex environments needed for life as we know it, suggesting that truly Earth-like planets could indeed be rare among the vast array of planetary systems.
Thus, the growing catalog of exoplanet characteristics has indeed led to a broader understanding that while star-like our Sun may be common, planets with conditions similar to Earth might be much rarer in the universe. This adds an important perspective to our search for extraterrestrial life and the study of planetary habitability.

ChatGPT lists some supplements to stay away from
There are several dietary supplements that many doctors generally disapprove of and may recommend against in most circumstances due to concerns about their safety, effectiveness, or potential interactions with other medications. Some of these include:
Kava: Often used for stress and anxiety relief, Kava has been linked to serious liver damage, including hepatitis, cirrhosis, and liver failure in some cases. Due to these risks, it is banned or restricted in several countries.
Colloidal Silver: Touted for its supposed immune-boosting properties, colloidal silver can cause serious side effects, such as argyria (a permanent bluish-gray discoloration of the skin) and potential kidney damage. It provides no known benefits in the body when taken orally.
Aristolochic Acids: Found in some traditional herbal remedies, aristolochic acids have been linked to kidney failure and urinary tract cancers. They are considered carcinogenic and have been banned in many countries, but they might still be found in some supplements.
DMAA (1,3-dimethylamylamine): Often included in weight loss and bodybuilding supplements, DMAA has been linked to serious health issues such as cardiac arrest, headaches, and tremors. The FDA has warned against its use due to safety concerns.
Yohimbe: Used as a treatment for erectile dysfunction and also in weight loss supplements, Yohimbe can cause erratic blood pressure, rapid heart rate, headaches, seizures, and kidney failure. It has significant potential for serious side effects, particularly in people with heart disease or hypertension.
Comfrey: While traditionally used to heal wounds, bruises, and for joint inflammation, comfrey has substances called pyrrolizidine alkaloids that can cause liver damage and are also carcinogenic. It is unsafe for ingestion and advised against even in topical use over large areas or on broken skin.
Bitter Orange (Synephrine): Commonly marketed as an alternative to the now-banned stimulant ephedra for weight loss, bitter orange can cause increased heart rate and blood pressure, leading to cardiovascular problems.
Doctors typically advise that supplements should not replace whole foods and a balanced diet. Before starting any supplement, especially for those with pre-existing conditions or who are taking other medications, it is crucial to consult a healthcare professional to assess potential risks and benefits.
Fortunately, I don't take any of these. I did try Kava (which I consider a drug, not a supplement) once, but didn't like it and wouldn't take something like that on a regular basis anyway. (Portland actually has at least one "kava bar," which seems to me to be a very questionable business venture, especially without prominent health warnings, of which, I gather, there are none). Yohimbe is pretty well known to be dodgy, and all the ephedrine-adjacents are pretty obvious stay aways.
The list is hardly exhaustive, especially if you include "traditional herbal remedies," which is sort of a euphemism for "raw plant material drugs." Quite a few of these, such as Ayahuasca (Banisteriopsis spp., often mixed with Psychotria viridis), are as dangerous as cocaine or opium, just not as well known. I'd say the jury is out on kratom (Mitragyna speciosa), which some doctors think of as just another addictive opioid-adjacent, but which remains legal and pretty widely used in many parts of the US. As a friend of mine wisely pointed out, just because plant alkaloids have been used in some traditional societies for a long time doesn't mean they're safe; different people, often with particular genetic profiles common in a regional population, may have very different tolerances and variations in liver function, such that what is a benign drug to some people may be toxic and quite dangerous to other people. This is even more true across species lines, interestingly: I read where the commonly used topical NSAID diclofenac is so toxic to cattle that a normal human dose can actually kill them. Just something to think about. Unfortunately, supplements and "herbals" aren't really regulated for safety. If you use them, it's caveat procuator.

Interesting analysis by ChatGPT of the phenomenon of increased "analytic" language prevalence over time
1. **Language Contact and Globalization**: With increased globalization and language contact, languages tend to simplify grammatical structures to facilitate communication between speakers of different linguistic backgrounds. Analytic languages often emerge as a result of this simplification process.
2. **Technological Advancements**: In today's digital age, where communication happens rapidly across various platforms, concise and straightforward languages are often favored. Analytic languages, which tend to have simpler grammar and morphology, are more conducive to digital communication.
3. **Education and Literacy**: As education becomes more widespread, there's a greater emphasis on literacy and education in many parts of the world. Analytic languages can be easier to learn and teach, especially for those who are not native speakers, compared to synthetic or polysynthetic languages with complex morphological systems.
4. **Urbanization**: Urbanization often leads to language simplification as diverse populations come together in cities, necessitating a lingua franca that is easy to learn and use. Analytic languages may be more suited to serve as this lingua franca due to their simplicity.
5. **Language Standardization**: Standardized forms of languages often tend to simplify grammatical structures for easier comprehension and learning. This trend can lead to the adoption of more analytic features in widely spoken languages.
However, it's essential to note that while analytic languages are becoming more prevalent due to these factors, there are still many synthetic and polysynthetic languages spoken by millions of people worldwide, particularly in indigenous communities and regions with strong cultural identities. Language evolution is a complex process influenced by a multitude of factors, and while there is a trend towards analytic languages, linguistic diversity remains rich and varied.
