The newly discovered microbe provisionally known as Sukunaarchaeum isn’t a virus.
But like viruses, it seemingly has one purpose: to make more of itself. scim.ag/4e6y0W2

Microbe with bizarrely tiny genome may be evolving into a virus
With DNA focused almost entirely on replication, newly discovered organism blurs the line between cells and viruses

I suspect that fact that the vast majority of LLM users don’t seem to have received this (really very simple!) message is because the AI companies have a vested interest in us not understanding it. “ChatGPT is smart, it just makes mistakes sometimes” is much more marketable than the truth.
Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.

Rising ocean acidity could reduce populations of phytoplankton, which may exacerbate climate warming.
More carbon dioxide in oceans could harm carbon-eating microbes, speed climate change
Increased ocean acidity could reduce populations of phytoplankton more than previously thought
