it's not that i ever doubted that being a barista was a skilled position, but my year-long effort to try to produce a half-decent latte at home has convinced me that a good barista is easily more skilled than virtually every c-suite executive on the planet

AI has come an enormous way since the early days...
Amazing precision and scholarly knowledge.
GoaLPleation for one is just around the corner in neuroscience research 😱

Canada loses its measles elimination status β€” as it happened | CBC

Misinformation is harmless, they say, it's just a different POV they say ... "Canada has lost its measles elimination status, the Public Health Agency of Canada says. Since the fall of 2024, Canada has recorded more than 5k measles cases in 9 provinces and one territory." www.cbc.ca/news/health/...

Govt's climate strategy: Let it burn Comment: The Government has relentlessly pursued policies that boost climate pollution – even if they cost more or jeopardise NZ's reputation, Marc Daalder writes

"If there is a coherent throughline to the totality of the Government’s climate policies, it can only be a willingness to
increase New Zealand’s contribution to global warming."

I'm with you.

We only need to look at how things are going in Australia to realise that, quite apart from the massive problems with digital IDing, it's unlikely to achieve what people hope it will.

Developers still aren't warming up to generative AI Developers do not in fact welcome our new AI overlords.

It seems like the more time game developers spend with generative "AI", the less impressed by it they are. In the most recent Game Developer survey of people working the industry only 13% expect these tools to have a positive impact on the industry, a decline of nearly half from the previous year.

I keep on coming back to the irrefutable fact that the people in New Zealand that don't want to address the impact of colonisation and argue "it's in the past, the current generation are not responsible for that" continue to enjoy benefits that flowed directly from that colonisation.

Slide is titled: You don't need to use LLMs. 

Science is a process of collaborative meaning making, by which we try to understand the world

Even if AI were perfect, we rely on it at our peril β€” it is not science if we (i.e., humanity as a whole) do not understand and cannot recapitulate all parts of it

I very, very rarely use LLMs myself. You can give yourself permission not to. Don’t FOMO yourself into it

Conclusion: Don't rely on something you don't understand and can't control

If you must use LLMS:

1. Treat them like you would an intern: only use them for things you can easily and thoroughly check

2. Make your process as robust as possible

3. Be aware of your own (human) cognitive biases

Getting nervous for the talk I'm about to give at a workshop about "using AI to drive impact" which features slides such as these.

Well now, would you look at that?

A massive study of NEARLY 300,000 people in the United States found that receiving an updated 2024-2025 mRNA COVID-19 vaccine REDUCED people’s risk of severe disease AND death in ALL age groups, REGARDLESS of immunity from prior infection or vaccination.

Lawyers, think hard before you use AI From Auckland University - Comment: Judges around the world have pulled lawyers up for submitting AI-generated material to the court that’s wrong. To those lawyers who do want to use it – here’s a war...

Excellent from my law colleague up at Auckland.

Legal AI is truth agnostic, often wrong, and time saved is often illusory.

ah, so = "the environment and attitude with respect to international students, staff and research. It is based on international-to-domestic ratios across staff, students and research collaborations"

Can't see how any of those would really be impacted negatively by Te Tiriti focus.

It doesn't matter how many times I'm made aware that there was a real human woman named "Rhoda Pidgeon" who lived in Christchurch I just ALWAYS find it funny.
That she got married to a William Haglund, and so upgraded from an avian ride to a mechanical one is just "chef's kiss".
