Workers describe a deteriorating culture at Block, the company behind Square and Cash App, where layoffs continue and employees are expected to use AI tools daily. After hundreds of workers were laid off in early February from Jack Dorsey's Block, some of the people remaining at the company say the internal culture has devolved to a point where performance anxiety is running rampant, using generative AI is required, and overall morale is rapidly deteriorating. Block is the parent company behind the merchant payment processor Square and the payment app Cash App. "Morale is probably the worst I've felt in four years," reads an employee complaint submitted to Dorsey in a recent all-hands meeting, a transcript of which was seen by WIRED. "The overarching culture at Block is crumbling."

The Boston startup uses AI to translate and verify legacy software for defense contractors, arguing modernization can't come at the cost of new bugs. Code Metal, a Boston-based startup that uses AI to write code and translate it into other programming languages, just closed a $125 million Series B funding round from new and existing investors. The news comes just a few months after the startup raised $36 million in series A financing led by Accel. Code Metal is part of a new wave of startups aiming to modernize the tech industry by using AI to generate code and translate it across programming languages. One of the questions that persists about AI-assisted code, though, is whether the output is any good--and what the consequences might be if it's not.

We introduce Dataset Grouper, a library to create large-scale group-structured (e.g., federated) datasets, enabling federated learning simulation at the scale of foundation models. This library facilitates the creation of group-structured versions of existing datasets based on user-specified partitions, and directly leads to a variety of useful heterogeneous datasets that can be plugged into existing software frameworks. Dataset Grouper offers three key advantages. First, it scales to settings where even a single group's dataset is too large to fit in memory. Second, it provides flexibility, both in choosing the base (non-partitioned) dataset and in defining partitions.

The AI search startup once predicted advertising would be a massive business. Perplexity is abandoning plans to put ads in its AI search product as the industry looks for sustainable business models that won't hurt user trust. The changes are part of a larger strategic shift for the company, which has long focused on disrupting Google Search's business. Google is changing to be like Perplexity more than Perplexity is trying to take on Google, said a Perplexity executive at a press briefing on Tuesday. Executives spoke to the press on the condition of anonymity.

Intel is launching'Ask Intel,' an AI virtual assistant built on Microsoft Copilot Studio to handle customer support cases and warranty checks. PCWorld reports this shift follows Intel's removal of inbound phone support in December, directing customers to online assistance instead. The AI system warns users its answers may be inaccurate, raising concerns about potential hardware damage from incorrect technical advice. If your Intel processor requires a warranty return or support, the first "person" you'll probably be dealing with at Intel will be an AI. Intel is rolling out "Ask Intel," an addition to its Intel support site, that runs on Microsoft Copilot rather than on human intervention. Ask Intel will appear as part of support.intel.com

OpenAI's Sam Altman: Global AI regulation'urgently' needed OpenAI CEO Sam Altman says the world "urgently" needs global regulation of fast-evolving AI, calling for an international oversight body. The "democratisation of AI is the only fair and safe path forward," he said.
