AI’s Real Bottleneck Isn’t Compute—It’s Memory

hightechz.net0 CommentsTechnology, , , ,
The AI Bottleneck Nobody's Talking About: It's Memory, Not Chips Somewhere between the hype cycle around GPUs and the race to trillion-parameter models, the actual hard problem in AI infrastructure got quietly sidelined. We've been watching the wrong competition. While everyone obsesses over whether Nvidia can manufacture enough H100s, the real constraint isn't compute power—it's memory bandwidth. And the companies placing bets on that reality are about to reshape how AI actually runs in production. The signal is unmistakable. South Korean chip startup XCENA just raised $135 million on the explicit thesis that memory, not compute, is AI's fundamental bottleneck.…

Data centers in Oregon might be helping to drive an increase in cancer and miscarriages

hightechz.net0 CommentsTechnology, Trending, ,
Morrow County, Oregon is home to mega farms and food processing plants. But it’s also home to several Amazon data centers. And now, some experts believe, that combination is leading to an alarmingly high concentration of nitrates in the drinking water that is driving up cancer and miscarriage rates in the area. Rolling Stone’s exposé details how Amazon, despite not using any dangerous nitrates to cool its data centers, is accelerating the contamination of the Lower Umatilla Basin aquifer, which residents rely on for drinking water. It’s a combination of poor wastewater management, sandy soil, and good old physics that…

A fire burns in a pavilion during the COP30 UN Climate Change Conference in Belém, Pará state, Brazil, on November 20th, 2025. | Photo: Getty Images "It's a wrap … Don't forget to buy an 'i survived Belém' shirt," reads the opening line of an email I got Saturday, the final day of highly anticipated United Nations climate negotiations in Belém, Brazil. The email was sent from Shravya Jain-Conti, the US climate diplomacy lead at the Global Strategic Communications Council (GSCC), who's been following these events for years. While she sometimes has tips on where to snag a cup of…

DOGE is no more, and in its wake, only chaos

hightechz.net0 CommentsTechnology, Trending
In April, Elon Musk began backing away from his role as head of DOGE. By June, he was more or less fully gone from DC. In his wake, he left a power vacuum and significant ill will that has apparently led to the dissolution of DOGE eight months before its charter expires.  To call Musk’s DC tenure contentious would be an understatement. As a man accustomed to getting what he wants and functioning as a powerful executive, he swept through Washington with a figurative chainsaw, slashing budgets, firing workers, and making audacious power grabs. Musk’s brash behavior angered government employees…

X’s messy About This Account rollout has caused utter chaos

hightechz.net0 CommentsBusiness, Technology
Yesterday X started rolling out a new About This Account feature, which included what country the account was created from and what country the account is “based” in (which is different from “connected via”). Head of product at X, Nikita Bier, was quick to say that there were “a few rough edges,” but promised they’d be resolved by Tuesday.  There have definitely been complaints about inaccuracies. The company even ended up removing information about where an account was created, saying the data “was not 100 percent,” especially for older accounts.  The reaction from users on X was, of course, totally…

Shocker: Elon Musk spends a lot of time on X posting bad political takes

hightechz.net0 CommentsTechnology, Trending
NBC News's David Ingram analyzed a month's worth of Elon Musk's X posts (our condolences). While what he was able to glean wasn't too surprising, it was still interesting to see the numbers all laid out. Between September 17th and October 17th, he posted 1,716 times, averaging a little over 55 posts a day. 49 percent of those were about politics, usually fringe. He seems particularly hung up on the race of people on TV and in movies, including going after child actors. Other things Elon likes to talk about? Crime, Tesla - oh, and of course, himself. Over the…

‘Jmail’ is like any other inbox, except this one has Jeffrey Epstein’s emails

hightechz.net0 CommentsTechnology
The more than 20,000 pages of Jeffrey Epstein emails released earlier this month by the House Oversight Committee have been enough to prompt more investigations into the convicted child sex offender and the people around him, like former Harvard president and OpenAI board member Larry Summers. Now, Luke Igel and Riley Walz have reformatted the source documents into a more familiar format for anyone looking into them by copying the Gmail inbox on a website called “Jmail.” Walz, who has previously authored stunts like a website that unearths long-forgotten iPhone clips on YouTube and a fake Manhattan steakhouse, said they…

Meta’s Hyperscape is ready to turn your real living room into a VR hangout

hightechz.net0 CommentsTechnology
Meta’s impressive, photorealistic digital replicas of real places built using its “Hyperscape” capture tech, which uses the cameras on a Quest 3 or Quest 3S VR headset to scan a room, have so far been solitary spaces. If you wanted to visit a virtual version of a room in your house (or of Gordon Ramsay’s home kitchen), you could only do it on your own. But beginning this week, Meta is rolling out the ability to share links that will let other people visit Hyperscape rooms with you in a Quest 3 or 3S VR headset or via the Meta…

Google’s new Scholar Labs search uses AI to find relevant studies

hightechz.net0 CommentsTechnology
Google has announced it's testing a new AI-powered search tool, Scholar Labs, that's designed to answer detailed research questions. But its demonstration highlighted a bigger question about finding "good" science studies. How much will scientists trust a tool that forgoes typical ways of gauging a study's popularity with the scientific establishment in favor of reading the relationships between words to help surface good research? The new search tool uses AI to identify the main topics and relationships in a user's query and is currently available to a limited set of logged-in users. The demo video from Scholar Labs featured a…

How much money do the most viewed YouTube videos make?

hightechz.net0 CommentsTechnology, Trending, , ,
Baby Shark Dance, the most-viewed video on YouTube, has generated tens of millions of dollars in revenue for the company behind it despite being in the children's category. With more than 16.4 billion views as of November 18, Baby Shark Dance by Korean company Pinkfong maintained its number one position, far surpassing Luis Fonsi's Despacito, which came in second with 8.86 billion views.
