I feel the same way about AI that I did about crypto when it started becoming a thing:

• All of the moral practices that make it possible are fucked beyond repair.

• It’s spawning some of the worst companies, and enriching some of the worst billionaires in the world.

• While there are some genuinely useful, practical applications for it, there are so few of them, and they have had so little positive impact so far, that it doesn’t even seem like it’s going to be worth it anytime soon.

@winterschon @nileane

True, but all the AI models in cancer, climate, ... research are fundamentally different from the ChatGPT type AI that is hyped at the moment. And the tech bros are less interested in those useful forms it seems.

I'd argue that it is part of the unethical practice, though, to conflate the two and attempt to disarm any criticism of the ChatGPT type AI pointing at AI use in cancer and medical research.

And it it indeed a shame if those uses get a bad reputation as a fallout from all the everyday AI hype.

I want to understand this, but I can’t grok more than the headline and the potential applications. Is anyone able to explain it to someone whose physics knowledge is Year 12 + Vertasium? Like, how do massless photons even have momentum?!

@evolvable

You can't explain photon momentum using classical mechanics. It's a quantum effect. This gives a good explanation of it:

""It has happened," wrote developer Arian van Putten in a social media post over the weekend. "The number one Google result was an official Pulumi documentation page that was clearly written by an LLM (it had a disclaimer that it was) and hallucinated an AWS feature that didn't exist. This is the beginning of the end.""

"Search quality has declined because search engines index low-quality AI-generated content and present it in search results."

Don't worry. We are moving towards a future where we will go to the old, wise woman for information again.

Let's just try and avoid the part where they get burned for frightening men with their smartness...

“Cruise companies are increasingly looking to offer sustainable and green travel opportunities for their passengers to explore their cruise destinations"

So one of the environmentally most damaging ways of travel is encouraging "green travel" for their passengers and the stone of contention are the bikes?

Wondering whether the recent rise in narrative CVs and applications has anything to do with LLMs doing the screening.

They don't seem to do well extracting information in tabular form, but reasonable when it's presented in narrative prose.

Pondering some form of e-Ink and am looking for recommendations. Ideal featureset:

Screen: ~7" - don't like holding a 10" iPad, and an expired 6" ereader seems a fraction small.
PPI: >~300
Wifi
Ability to sync to/from CalibreWeb

I'd rather not pay Amazon for their products so that probably excludes the Kindles unless they are outstandingly worth it. Thoughts?

Alcohol consumption in the EU has declined by 0.5 litres per person between 2010 and 2020. However, there are several countries where consumption increased, Euronews reports:

Statistisches Bundesamt: Wirtschaftsleistung im Sommer geschrumpft

Besonders die Zurückhaltung beim Konsum belastete die deutsche Wirtschaft im Sommerquartal. Das Bruttoinlandsprodukt verringerte sich laut Statistischem Bundesamt von Juli bis September um 0,1 Prozent. Die Ökonomen hoffen auf 2024.

Hmm. Muss man "Zurückhaltung beim Konsum" wirklich als negativum darstellen? In 2023?

I decided I need a new hobby and a musical challenge.

I never played finger-style guitar, so learning this 13-string instrument is quite a daunting prospect.

Looking forward to my first lesson next week with @jacobheringman at the in Saltaire.

    If it's only images, then epub is not the right format. But then, if it's only images, and the images contain text then that'll pose accessibility issues.

    There are some comic formats, that may be suited for image only.

    Is there any digital data storage hardware and associated encoding that has an intended archival life of at least 1000 years without electricity?

    I know it's an old question, but given that paper or palm leaf manuscripts last that long, is there any standard out there which would support civilizational timescales?

    No bonus points for guessing why I'm wondering about this.

    Really good question. Wondered about that myself recently. What was Asimov's solution in Foundation?

    Whilst we all focus on the catastrophe that is ever-increasing atmospheric CO2, methane levels are shooting up - and methane has a much higher warming potential than CO2.

    For some definition of "dealing with it", they are. My cynical self thinks they are intentionally kicking the can down the road, until geo-engineering solutions will become inevitable and accepted in by the general public.
