Qualcomm raised the curtain on a variety of artificial intelligence, 5G, and Wi-Fi technologies at Mobile World Congress Barcelona, which runs through Thursday. The San Diego-based chip designer unveiled an AI Hub it says will help developers create voice-, text- and image-based applications using pre-optimized AI models. Qualcomm’s flagship AI chips — the mobile Snapdragon 8 Gen 3 processor and the PC-centric Snapdragon X Elite — were announced last year. With the first splash of products now heading to market the company is promising to push the boundaries of 5G and 6G. Read more

Researchers at China’s University of Shanghai for Science and Technology have invented an ultrahigh density optical disc format they claim can store up to 1.6 petabits — more than 1,500 terabytes, or 125,000 gigabytes — of data. While the new discs are said to look like typical Blu-rays, the data is written to one hundred layers in a 3D stacking architecture by a 54-nanometer laser that is about one-tenth the size of visible light waves. The same laser is used to read the data back. The tech is said to present “a promising solution for cost effective, long-term archival data storage.” Read more

Florida’s legislature has passed a bill banning children younger than 16 from having social media accounts despite some pushback from Governor Ron DeSantis, who said he will be wrestling with whether to sign the measure into law. Due to a procedural requirement, DeSantis will have to sign or veto the proposed legislation before lawmakers conclude the current session in a matter of weeks. He has expressed dissatisfaction with the lack of a provision to let parents override the restriction, which would curtail access to the most popular sites, potentially impacting TikTok, Instagram, Facebook, Snapchat and YouTube.

Community message board and social news aggregator Reddit, founded in 2005, has filed to go public on the New York Stock Exchange in an IPO observers say may be complete in a matter of weeks. It is the first social media company to go public in many years, with Snap Inc.’s 2017 offering cited as the most recent stock market splash. Reddit’s bankers are reportedly seeking a $5 billion valuation, about half the $10 billion it was valued at for a 2021 private funding round. Reddit filed with the SEC the same day it announced an “expanded partnership” with Google to use Vertex AI. Read more
