If you’re a journalist who’s still on Twitter, from now on in your writing you have to replace “the American people want” with “troll bots in Eastern Europe demand”
Being there makes your judgment suspect. I don’t care how savvy you think you are, you’re marinating in a disinformation campaign.

It’s widely known (and, I think, pretty uncontroversial) that learning requires effort — specifically, if you don’t have to work at getting the knowledge, it won’t stick.
Even if an LLM could be trusted to give you correct information 100% of the time, it would be an inferior method of learning it.

Relying on ChatGPT to teach you about a topic leaves you with shallower knowledge than Googling and reading about it, according to new research that compared what more than 10,000 people knew after using one method or the other.

Australia is known as a country of innovators, but with a combination of brain drain, continuous cuts, and a loss of critical science projects, is Australia losing its edge?

In the latest Global Carbon Budget, the estimate of the ocean carbon sink was increased by 0.8 Gt of CO₂ due to methodological changes.
Each mCDR deployment aims to remove a tiny fraction of that, so if people think we have the methodology to do proper MRV for mCDR right now, they're delusional. 🌊
