Hello, I'm Chris. All sorts of intranet, digital workplace and internal comms useful since 1996 and now partner at Spark Trajectory in UK. 17 years on the other place but it became a read-only medium when everything all got a bit fraught. Here to share and find interesting people and ideas.
Claiming AI agents have autonomy is like me claiming my oven roasts a chicken on its own, between me putting it in and taking it out.

Duolingo’s increasing desperation to sell me their AI enhanced version is getting kind of off putting. Mates, make it part of the core offering or move on.

It's fascinating to me about how the intentions of the AI companies (fire all the people) and the uptake of AI in business (get it to do the work of people we fired already) are in conflict.

When the AI crash comes, there is going to be an awful lot of "Poor me my smol bean startup has died we were only trying to replace thousands of actual jobs."

“Current architectures of LLMs cannot imagine, but they can sequence … For the same reason that a dog can go to church but a dog cannot be Catholic, an LLM can have a conversation but cannot participate in the conversation.”
I've been re-acquainting myself with NNs, transformers and LLMs this week, so these are early thoughts. But I am starting to think about language without the capacity to imagine language, i.e., an LLM unable to imagine itself participating in language. mail.cyberneticforests.com/what-machine...

Governance is the dull magic you need to manage anything. Governance = (Clarity + Meaning + Accountability) x Attention.

Nice illustration of AI and Jevons' paradox. AI makes the amount of cases in Brazilian legal system go up.
“We note that the use of AI, in the end, rather than diminishing litigation, is increasing it…[AI] may be a solution, but no one’s sure if it will actually work.”
AI is helping judges to quickly close cases, and lawyers to quickly open them
Brazil’s overburdened courts and lawyers are adopting artificial intelligence. But experts wonder whether it serves justice.

Jo's travel adventures are one of my favourite forms of content in any medium.
Hei hei from the Hvalross in Vardø, a fish port on a butterfly-shaped island in the Barents Sea, starting point for the #Schengen200 adventure. Schengen is 40 in 2025 and we’re attempting the longest point-to-point journey within it, by public transport, in about 200 hours. bsky.app/profile/poli...

LinkedIn is truly the purgatorysite. What sort of person comments on people like Satya Nadella's posts and why are they so obsequious when they do?

It's really not fucking complicated. Anyone attributing aspects of consciousness to an LLM is either a charlatan, mistaken or is experiencing a psychotic episode. "Divided" Ha!

Generative AI is 1st new tech marketed in post-Moore's Law era.
In previous decades, if new digital tech needed more or cheaper computing power to work & make economic sense, a few more years of Moore's law would solve.
But exponential growth in transistor density is stalling now...
