Exit through the back

Brazilian investment funds registered a net withdrawal of BRL 82.1 billion in the first quarter of this year.

Which explains: with the Selic at 13.75% per annum, investors have opted to invest directly in fixed income securities, assesses Pedro Rudge, vice-president of Anbima.

It wasn’t just in investment funds. Savings investments registered a net withdrawal of BRL 6 billion in March, after a record redemption of BRL 11.5 billion in February.

• It could also be a sign that people are withdrawing money that was saved to pay everyday bills.

In numbers: among the funds, the highlight is the withdrawal of fixed income investments, which boomed last year as a result of high interest rates.

• After registering BRL 108.4 billion in funding in the first quarter of 2022, funds in the category had withdrawals of BRL 12.2 billion in the first three months of this year.

• Multimercados had the highest redemptions, of R$37.4 billion, followed by equity funds, with withdrawals of R$23.9 billion in the period.

Dream illustration?

From magnetic resonance imaging of brain activity, researchers in Japan managed to reconstitute with AI (artificial intelligence) the image of a train that had been shown to a person.

Understand: the study was done at Osaka University with four people who each looked at 10,000 pictures while undergoing MRI scans.

• From these data, the researchers used computational models similar to the one used in the Dall-E to generate the images, translating brain stimuli into images compatible with the original ones.

Why it matters: technology can help scientists map the code behind how the brain works.

• That is, we can imagine that –in a reality still far from the current one– it would be possible with this new technique to reproduce images of dreams or thoughts on computers.

More about AI

Rune Nyrup, a philosopher specializing in AI, says in an interview with Sheet that the convincing speeches of chatbots like ChatGPT can lead to wrong conclusions, giving an idea of ​​​​a competence that they do not have.

Opinion: Italy’s data protection body has not banned ChatGPT in the country, it has only ordered it to stop processing resident data, say researchers Luca Belli and Walter B. Gaspar.

take a break

• To watch: “Air: The Story Behind the Logo” – in theaters.

Starring Matt Damon and Ben Affleck – who is also the director –, the film tells the story of the shoe dedicated to basketball star Michael Jordan, who transformed the history of Nike.

• Damon plays Sonny Vaccaro, an employee of the sporting goods brand that sponsors the athlete at the beginning of his career.

The film deals more with the commercial dispute at the company than with Jordan’s career, which at most is seen from the back in meetings. Who has more prominence is Viola Davis, in the role of the mother of the player.

Review: “Air” uses corporate tennis history to discuss media myths, opines Pedro Strazza.
