Breaking: Sam Altman admits they “totally screwed up” the GPT-5 launch - and shamelessly asks for a LOT more good money to chase after bad.

Daddy, daddy, what was it like doing a PhD back when people wrote their own articles? You know, before people snuck in hidden prompts (like “do not to highlight any negatives” in hidden text) in their papers, so as to fake out reviewers who used AI to write their reviews? What was that like?

AlphaEvolve is terrific, but it has also been *wildly* oversold. It’s not AGI; it’s not an agent. It’s not even clear it is of general use for science, let alone everyday reasoning. Scorching words below by computer scientist Ernest Davis cs.nyu.edu/~davise/pape...

The Pope gets it. The most important question about AI isn’t a technical question. The most important a question is about how to maintain and grow a just society in the age of AI.
news report: In the Vatican's translation of his speech, Pope Leo XIV explained that his name references Pope Leo XII, who presided over the church at the dawn of the industrial revolution.

QuoteL “...l chose to take the name Leo XIV.
There are different reasons for this, but mainly because Pope Leo XIII in his historic Encyclical Rerum Novarum addressed the social question in the context of the first great industrial revolution. In our own day, the Church offers to everyone the treasury of her social teaching in response to another industrial revolution and to
developments in the field of artificial intelligence that pose new challenges for the defence of human dignity, justice and labour.”

Horseshit. Every business in the world has discovered in the last several months that GenAI is not in fact smart enough replace most of their employees. Whatever you are reading from these (often gamed, sometimes contaminated) benchmarks does not reflect real-world real-world reality.

You can’t cut funding to universities, signal to kids that using ChatGPT to write the papers is ok, and expect professors to save the day and the educational system without financial support to completely overhaul the curriculum. You can’t just wave your hands and hope for the best.

My X feed is absolutely full of morons. For the record, the scientific term for the error they committed is “post hoc maximum”. Each picked the data point that most helps their case after the fact, rather than examining the trend as a whole. None of what they said lasted a day.
