Patients across the country have been unable to get their prescriptions filled as health tech company Change Healthcare responds to a cyberattack.

Why it matters: It's still unclear when Change Healthcare will return to normal operations, and until then, local pharmacies that rely on the company to process payments through patients' insurance say they're facing outages and delays in filling prescriptions.

U.S. regulators must hold companies accountable for their poor cybersecurity practices, Homeland Security Secretary Alejandro Mayorkas told Axios.

Why it matters: U.S. critical infrastructure has proven vulnerable not only to highly skilled nation-state hackers who lurk in American infrastructure, but also to low-level hackers who can simply guess a utility operators' password.

AI chipmaker Nvidia topped $2 trillion in market cap on Friday less than nine months after crossing the $1 trillion threshold.

Why it matters: AI-drunk investors have bid up Nvidia, whose advanced chips power AI systems, to bubble-like levels. The company's stock chart parties like it's 1999 — and we all remember what happened to the dotcom era darlings a year later.

Federal Reserve Bank of New York president John C. Williams weighed in on the potential impact the artificial intelligence boom could have on the economy — specifically, whether it will make workers more productive over the long term.

Where it stands: Whether or not the current productivity boom is sustainable — especially if and when the supply-side effects Williams mentions wear off — might come down to the impact of AI.

It isn't just Nvidia. A new cadre of hot stocks is now riding the artificial intelligence boom.

Why it matters: The bull market has been running since October 2022, but the near-euphoria surrounding all things AI seems to be provoking renewed feelings of friskiness among investors.

The big AT&T network outage was a productivity catastrophe for commuters across the country Thursday, but remote workers were totes fine, Bloomberg reported.

"Chief AI officer" is one of the hottest new job titles, but some experts say AI strategy should be everyone's job.

Why it matters: Many organizations have decided that AI is too important and complicated to rely on one executive to develop and manage their strategy.

AT&T says Thursday's outage which left thousands of customers without service and unable to call 911, was "not a cyber attack," the company believes.

Why it matters: Despite threats from nation-state hackers in China and Russia, it's still statistically more likely that a network outage would be caused by misconfigurations or faulty settings.

Cell service to thousands of Americans was restored after network outages on Thursday left customers with AT&T and other service providers unable to place calls, send texts or use the internet on their mobile phones.

Why it matters: The disruptions left some people unable to contact emergency services by dialing 911, prompting safety warnings from authorities.

A new report from plagiarism detector Copyleaks found that 60% of OpenAI's GPT-3.5 outputs contained some form of plagiarism.

Why it matters: Content creators from authors and songwriters to The New York Times are arguing in court that generative AI trained on copyrighted material ends up spitting out exact copies.

AI makers' desperate need for millions of powerful chips took center stage on Wednesday as the world's most valuable chipmaker, Nvidia, reported another quarter of massive revenue growth and longtime leader Intel reported progress on reinvigorating its manufacturing operation.

Why it matters: Nvidia's fortunes have soared along with demand for its chips to train and run AI systems — but the rest of the semiconductor industry stands to get a major boost from AI, too.
