This is excellent. We just need another 50 or 100 similarly minded billionaires. Though taxes are more accountable and probably yield less idiosyncratic outcomes

Clearly this result is model-dependent: those raw skulls are indeed quite distorted, and your phylogenetic analysis is based on a virtually reconstructed skull. How sensitive are your conclusions to model parameterisation or model assumptions?

Five people stand in a row on a terrace with a stone balustrade, smiling at the camera. From left to right: Saul Manzano, Graciela Gil Romera, Luke Aurilis, Juan Ivars and Lynne Quick. Behind them rises Cape Town’s Table Mountain, lit by the soft colors of dusk. The group looks relaxed and cheerful, dressed casually in jackets, sweaters, and trousers. The city spreads out below the terrace with rooftops and buildings visible in the fading light.

A wide view of Cape Town at sunset, framed by two iconic mountains. On the left rises the flat-topped Table Mountain, while on the right stands the conical peak of Lion’s Head. Below them, the city stretches out with clusters of houses and buildings nestled among green hills. The sky glows in soft shades of blue, purple, and gold as the sun dips behind the mountains, casting a tranquil light across the landscape.

One of the truly compelling features of using an LLM as a coding tutor, rather than, say, asking human coders for advice at Stack Overflow, is that the LLM is polite, never complains about your failure to provide a reproducible example, and is uninterested in being an arsehole.

resources of countless other planets, swoops down on the Earth like a swarm of 'grasshoppers from space' intent on turning it into a wasteland? Those aliens are us. Only the other planets still left to be destroyed after Earth do not exist. We would do well to understand this as soon as possible.
The consumption of organic material produced by other living beings is typical of animal life. Not being able, as plants are, to fix the energy of sunlight autonomously, animals must rely on the predation of other living beings to ensure their survival. This is why plants are always pictured at the bottom of those typically pyramidal illustrations that we see everywhere bearing the name of the food pyramid, or the ecological pyramid, or the trophic pyramid.
Whatever the name, the concept is always the same.
There is a pyramid with plants, the producers, occupying the lowest level, and then proceeding upwards through the various trophic levels. First, the herbivores that eat plants, then above them the carnivores that eat meat, and then the omnivores that eat both plants and meat, and so on, until you get to the apex predators, who are at the top of the food chain.
I have always found these representations of plants as the lowest level of a pyramid to be rather ungenerous, not to say wrong. It would seem to me more correct that the top should be reserved for the organisms that produce chemical energy, rather

I agree LLMs are not built for accuracy. But the coding and statistics I refer to are also 'research'. I wonder if LLMs' comparative accuracy at coding-maths-stats is merely because that part of the corpus is very consistent, in tone and content. Fortuitous, in other words.

That's just not a sensible generalisation. It somehow does a rather good job of rendering real content, and doesn't bullshit or try to flatter the user, in numerate, rather emotionless, topics such as computer coding and statistics
