![Slide title: Thank You for Hosting Remote Talks
Body of slide:
Many researchers cannot travel because of:
- Visa issues
- Disability
- Personal or family health issues
- Money - personal, university, country
- Family responsibilities
- Work responsibilities
- (Climate change & environmental cost)
[Highlighted] Remote events help tie us to the community!](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:pa7qh66jfhgfev77jyz7fogh/bafkreigtkcvtgnwuy7kiqtpazfm6ea67mdhuka6tvecrmbazoc4d6v3gna@jpeg)
New (*draft) slide just dropped, that I want to include at the start of all my online talks. Thoughts or feedback?

The goal of Spotify’s algorithm isn’t to help you discover new music, its goal is simply to keep you listening for as long as possible. It serves up the safest songs possible to keep you from pressing stop.

When you are using the "AI" framing, does the way you talk about "AI" carry water for the Sam Altmans of the world? That is, are you helping to paint a picture of their tech as inevitable, all powerful, and/or anything other than commercial products?

Love the phrases "Cognitive Cost" and "Executive Function Theft" to pinpoint how exhausting it is to be constantly bombarded with apps telling you to use AI. I've been calling it "Corporate pressure" and "Force feeding". It's quite a lot right now. Seems a bit desperate tbh.
The #ExecutiveFunctionTheft of having to opt out.
Feeling annoyed at the cognitive cost of having to dismiss all the offers of "AI" assitance every time I use Acrobat to provide feedback on documents my students wrote. (NO I do NOT want an "AI" summary of this. In what world???)

Right, so maybe a better way to frame the question of the thread is, what are good ways to teach people how to meaningfully contribute w/o setting themselves up as smarter / better / faster / superior?

If you ever want to see a human BSOD, bring up one of these many cases and ask your leadership chain if they are including any safety training or support alongside the mandatory universal adoption of LLMs at work. The stares are so blank you could paint on them with watercolors.

2. Every single university that has invited OpenAI into our midst should be asked to account for their choices.

Another person who started down this path from the most “innocuous” advertised uses of ChatGPT: homework help. I have been struck by the cases of people getting lost in delusions after using this product for work or school: ie the use cases we are supposed to encourage as faculty.

OpenAI pirated large numbers of books and used them to train models.
OpenAI then deleted the dataset with the pirated books, and employees sent each other messages about doing so.
A lawsuit could now force the company to pay $150,000 per book, adding up to billions in damages.
