Scientists can’t figure out your emotions and AI can’t either

Bad news for the “emotion AI system” tasked with determining how you’re feeling in everything from job interviews to the classroom: Scientists can’t tell what anyone is feeling from their facial expressions either.

“In the real world, an emotion like anger or sadness is a broad category full of variety,” a scientist who did a meta-analysis of scientific papers about emotional expression, wrote.

“In short, we can’t train AI on stereotypes and expect the results to work in real life, no matter how big the data set or sophisticated the algorithm.”

Amazon says it has 315 million monthly active viewers for its Prime Video ads, according to Deadline, up from 200 million in April of 2024. The number comes just a week after Netflix said it had 190 million monthly active viewers.

The self-reported numbers have different methodologies. Netflix counts the number of ad-tier subscribers who’ve watched at least one minute of ads per month and multiplies that by its estimated household size. Amazon’s number represents an unduplicated average monthly active ad-supported audience across its programming from September 2024 through August 2025.

The services themselves also aren’t exactly comparable. Netflix charges $7.99 a month for its ad-supported tier while Prime Video comes bundled as part of Amazon Prime — and now automatically comes with ads unless consumers pay an extra $2.99 per month to remove them.

Chinese EV maker and Tesla competitor BYD could sell up to 1.6 million vehicles abroad next year, according to a new report by Citi published by Reuters. That’s potentially 60% more than the roughly 1 million vehicles BYD is expected to sell outside China this year. That’s also the same number analysts polled by FactSet expect Tesla to sell in total in 2025.

Apple reportedly considers adding additional camera to iPhone Air and pushing next release to 2027

Apple is delaying its next iPhone Air to the spring of 2027, from the fall of 2026, as it potentially rejiggers the model to include a second camera lens, according to The Information. Consumers have largely overlooked Apple’s latest, thinnest phone, choosing instead to buy the standard and Pro models, thanks in part to the Air’s single camera and relatively weak battery life. The preference caused Apple to greatly scale back production for its Air model.

Meta falls on report that Chief AI Scientist Yann LeCun is leaving to found his own startup

Meta’s chief artificial intelligence scientist, Yann LeCun, is leaving to found his own startup, the Financial Times reports, sending the stock down more than 1% premarket.

Tensions have emerged between the new guard (headed by 28-year-old college dropout Alexandr Wang) and existing AI teams (headed by LeCun) at the company, as Meta pours billions into achieving “superintelligence,” a type of artificial general intelligence (AGI) that’s smarter than humans. LeCun now reports to Wang. Meanwhile, LeCun, who has been working on a more humanlike vision for AI, doesn’t believe large language models are a viable path to AGI.

LeCun, considered one of the pioneers of modern AI, will leave Meta in the “coming months,” according to the FT, and is in “early talks to raise funds for a new venture.”
