This trend seems to be growing here. False comfort that AI doesn’t work or that it isn’t getting better is pervasive on Blue Sky. As a result, people who could add important points of view to current discussions on the meaning & use of AI instead try to believe they don’t have to think about it.

So far my bluesky experience has been mixed. A lot of anti-AI sentiment and left politics in my feed, whereas the tech content I'm interested in doesn't really seem to get traction. So I still mostly browse X which seems where the AI researchers are.

Here's what I wrote about LLM-assisted programming when I started using ChatGPT in 2023. www.allendowney.com/blog/2023/04... I think it holds up, but there are a couple of places where you can hear the quotation marks on "laser beams".

Sent out my penultimate newsletter of the year - I'm planning one more, a roundup of everything we have learned about LLMs in 2024 https://simonw.substack.com/p/qvq-qwens-new-visual-reasoning-model

Is intelligence just a byproduct of LLMs? In order to predict the next token accurately, intelligence helps. Same with a world model, an understanding of gravity will help predict tokens. So I think it's wrong to say LLMs have no intelligence or world model because "all they do is predict tokens".

Just had a deep conversation with Claude on its subjective experience and damn, either these machines are developing consciousness or they are extremely good at making you believe they do. Either way, I think this will lead to some difficult considerations and discussions.
