Outro caso: precisava descobrir o autor de uma citação. Joguei entre aspas no Google e ele foi incapaz de me entregar o link do artigo original mesmo estando numa revista on-line. Ele insistia em debater o texto da citação na versão IA de resultado. Acabou o buscador!

🚨 Virada em curso 🚨
💡Artigos escritos por IA superam textos humanos. Em 2025, 53,5% dos textos na web são IA. Áudio/vídeo seguem atrás.

💡Muda também o modelo das empresas de IA. Antes IA era ferramenta prática. Agora empresas querem "engajamento".

Essa semana fiz uma pergunta ao Deepseek. Qdo ele respondeu, pedi as referências da resposta. Ele deu. Tudo inventado, claro. Pedi referências reais e verificáveis, ele pediu desculpa e ofereceu alternativas. Adivinha: ele inventou de novo e ainda CRIOU LINKS FALSOS para eu “conferir” q eram reais 😫

"O chatbot do Google, aliás, foi o que se saiu pior no teste, com 76% das respostas apresentando algum problema significativo, especialmente no uso de fontes. O dado é mais que o dobro dos outros assistentes. Em seguida no ranking, vêm Copilot (37%), ChatGPT (36%) e Perplexity (30%)."

Chatbots têm erros graves como fonte de notícias 45% das vezes, diz estudo

Ao todo, 81% das respostas dos robôs apresentaram pelo menos um problema

Wanna feel OLD?

Reddit post: “how bad actually was COVID?” That reads: “ was around 9 years old when the pandemic started and I barely have any memories of it. I do remember the lockdown, wearing masks everywhere, online school, getting sick with it twice (it felt like the normal flu), but my family still went out like to the beach or the mountains. I guess it’s because my mom shielded me from the news and all but idk.”

🚨SCOOP🚨 DHS ordered OpenAI to identify a user who'd made 2 specific prompts.

User was anonymous and accused of helping run 15 child abuse sites. They'd disclosed the prompts to an undercover agent.

First example of what I'm calling a reverse AI prompt search.

You can always count on legacy media to ventilate 'both sides' of fascism.
To ensure there is 'balance' between truth and propaganda.
To pretend that they are dispassionate observers,
rather than enablers of the demise of democracy.

A Financial Times infographic titled “The circle of AI: how capital revolves in the tech ecosystem.” It illustrates financial flows among OpenAI, Oracle, CoreWeave, Nvidia, and AMD. Arrows represent relationships: solid blue for customers, dashed blue for investors, light blue for repurchase agreements, and pink for vendor financing or favorable terms. Key figures include: OpenAI as a $36bn customer of Oracle and $22.4bn customer of CoreWeave; Oracle investing $300bn in OpenAI; Nvidia investing $100bn in CoreWeave and $40bn in Oracle; Oracle as a $0.75bn customer of AMD; and several TBD (to be determined) financial connections. Sources are company data and Morgan Stanley research.
