Musk Faces Brazil's Supreme Court over Free Speech Showdown

Elon Musk faces an inquiry from Brazil's Supreme Court Justice Alexandre de Moraes due to his public stance against a court order to block certain accounts on Twitter, which is known as X in the search results. Musk, as the CEO of Twitter, has vowed to reinstate these accounts and encouraged users to use a virtual private network (VPN) to bypass the restrictions. This defiance has been celebrated by right-wing political leaders in Brazil.

Justice de Moraes initiated the investigation, which includes potential charges of disseminating false news, obstruction, criminal organization, and incitement. The judge has emphasized that freedom of speech is not "above other rights" in Brazil and that Musk's actions may be seen as a disrespect to Brazil's sovereignty. If Twitter fails to comply with the court's mandate, the company could face a fine of about $20,000 per day for each account that is not blocked.

The investigation also involves Musk's alleged role in a network of digital militias, which have been accused of spreading defamatory fake news and threats against Brazilian Supreme Court justices. The Brazilian Supreme Court has been actively regulating social media platforms to address misinformation and hate speech, particularly in the context of Brazil's presidential election in October 2022 and the subsequent insurrection attempts.

Musk has criticized the Brazilian Supreme Court for suppressing free speech and violating the Brazilian Constitution. However, Justice de Moraes has defended his actions as necessary to protect Brazilian democracy and purge social media of fake news, while critics argue that these actions infringe on freedom of speech.


Spotify launches AI-prompted playlists

Spotify has indeed launched a feature that incorporates AI technology. While the search results provided do not specifically mention "AI-prompted playlists," they do discuss various AI-related developments at Spotify:

  1. Spotify Jam: This feature allows friends to collaborate on a single playlist in real-time, regardless of their location. Premium users can start a "Jam" session and invite others to contribute to the playlist.

  2. Spotify Duo: A subscription plan for two people, offering individual premium accounts and shared billing. Spotify Duo also integrates with Alexa devices, allowing voice commands for music control.

  3. YouTube Music AI-Generated Playlist Art: Although not directly related to Spotify, this feature from YouTube Music allows users to create AI-generated playlist art using text prompts and visual themes.

  4. Spotify Wrapped 2023 with AI DJ and Blend: Spotify Wrapped 2023 introduced an AI DJ and Blend, which allows friends to combine songs they both like into a single playlist.

While these developments involve AI technology, they do not explicitly describe playlists that are generated solely from AI prompts. The LinkedIn post from September 21, 2023, mentions "Spotify Launches AI-Prompted Playlists," but the provided link does not offer more details or a direct source for this information. Therefore, the search results do not confirm the launch of AI-prompted playlists by Spotify as of the latest available information.


Meta custom AI processor

Meta has recently unveiled the next-generation of its custom AI processor, the Meta Training and Inference Accelerator (MTIA). This chip is designed to power the company's AI workloads, particularly in serving ranking and recommendation models for its apps and services, including Facebook, Instagram, and WhatsApp.

Key aspects of the new MTIA include:

  • Built on a 5nm process, which is more advanced than the 7nm process used in the previous MTIA v1.
  • Physically larger design with more processing cores than its predecessor.
  • Offers 128MB of internal memory, which is double the amount in MTIA v1.
  • Operates at a higher average clock speed of 1.35GHz compared to 800MHz in MTIA v1.
  • Delivers up to 3x better performance compared to MTIA v1 for specific key models.
  • Currently deployed in 16 of Meta's data center regions.

Meta aims to use this custom silicon alongside commercially available GPUs (Graphics Processing Units) to achieve greater efficiency, as the company controls the entire hardware stack. The new MTIA is not yet used for generative AI training workloads, but Meta has several programs underway exploring this possibility.
