Hello those drifing through BlueSky.
I mostly post about these:
* My experiences with students in the Maths Learning Centre
* Maths and maths teaching thoughts I have, including live problem-solving
* Books I read (mainly childrens fiction)
* Observations and photos of things I see in the world

I don’t know if anyone else notices or cares, but when I see a presentation in which the speaker uses obviously generated-AI images to illustrate their slides, it makes me immediately less confident in whatever other content they’re presenting.

I don't know what is real and what is deep faked and what is LLM disinformation, and I'm *so exhausted* of having to figure out! So if you put some evidence up front that you're using AI it is a relief to be able to discount your existence.

THREAD.
3 years ago, with no warning, a brilliant orange farm cat wandered over from the draughty barn where he had been living, in rural Cornwall, and decided he wanted to live with us instead.
We decided to call him Jim.
This is the first photo I took of him, on that night: December 1st, 2022.

Went to the social media platform formerly known as Twitter to check something I said a few years ago, and this little blue thing hovered around offering for Grok to summarise and explain people's posts to me. Gross. Had to get out of there fast.

There's a part of learning, which generative AI completely turns into dogshit, which is *doing something you could not have done before*
Whether it's drawing, playing an instrument, solving a physics problem, organizing an essay, you find yourself doing easily what previously you found overwhelming
