The EU AI Act prohibits "high-risk" AI practices, while reserving the right for law enforcement to use these
so-called high-risk practices for law enforcement with "appropriate safeguards".

AI Controlled by Big Tech: The optimism for AI to be a competitive and vibrant field dominated by various small to medium companies must come to the realisation that tech giants, holding majority of infrastructures necessary for AI still have a substantial influence. More about it here:

If we’re not careful, Microsoft, Amazon, and other large companies will leverage their position to set the policy agenda for AI, as they have in many other sectors.

Scheurer et al demonstrated that Large Language Models (LM) are competent and capable of lying when put under pressure. The researchers put LMs as trading agent and discovered that even when not trained to be deceptive the LMs will use misalignment and strategic deceptions when put under pressure. GPT-4 models displayed a higher tendency of misalignment, strategic deception and doubling down on strategic deception far more likely than older models. Letting the LMs write out their chain of thought on a ‘scratchpad also increases their likelihood to be dishonest.

More about it here:

We demonstrate a situation in which Large Language Models, trained to be helpful, harmless, and honest, can display misaligned behavior and strategically deceive their users about this behavior without being instructed to do so. Concretely, we deploy GPT-4 as an agent in a realistic, simulated envir...

Recently, 21 years-old Luke Farritor used the help of AI to decipher the Herculaneum Papyri a collection of papyri scrolls found in Herculaneum, neighboring the city of Pompeii. These scrolls, damaged by the Vesuvius Eruptions and exposure to the elements rendered almost any attempt at reading or even unscrolling them them nigh-impossible. While modern advances enabled the use of CT-Scans to ‘virtually unwrap’ the scrolls, it was not until August 5, 2023 that Casey Chandmer discovered the evidence of ink on the scrolls. This was the first step towards identification of letters, which was finally done by Luke Farritor using AI trained on images of ink traces, shown here as crackles.

But they are also the ones who tell you who to support for elections. This year the local kumicho (head of kumi) came to give us leaflets for a ci...
