My first comment piece in @theguardian.com is on a topic very close to my heart; the threat that the #ClimateCrisis poses to my local community in South Wales.
Here's a thread with a few extra thoughts from me 🧵

There is no way to achieve "deep, rapid and sustained reductions in global greenhouse gas emissions" without a rapid transition away from fossil fuel burning. The international scientific assessments are very clear on this point. One could view a focus on other sources as intentional deflection.

It’s blowing my mind that schools, universities, public services would run headlong into this. We spent 15 years documenting black boxes. This is a black box in a black hole!
I don't understand how anyone can watch how blatantly Grok is manipulated to answer the way ownership desires it to and then act like the other LLM chatbots couldn't possibly be similarly but less obviously compromised to produce responses in whatever way corporate interests and priorities dictate.
