Nvidia Showcases AI Chips as It Shrugs off DeepSeek

Nvidia chief Jensen Huang is expected to showcase cutting-edge chips for artificial intelligence (AI) and quantum computing on Tuesday, shrugging off talk of China's DeepSeek disrupting the market.

Huang's keynote presentation at Nvidia's annual developers conference should pack the SAP Center in the Silicon Valley city of San Jose, where the Sharks NHL hockey team plays.

Industry watchers expect Huang to spotlight Nvidia's latest Blackwell line of graphics processing units (GPUs), including new updates in the works.

The AI boom propelled Nvidia stock prices to stratospheric levels until a steep sell-off early this year triggered by the sudden success of DeepSeek.

The stock, one of the most traded on Wall Street, is down more than nine percent this year despite a recent rebound from a March low.

China-based DeepSeek shook up the world of generative artificial intelligence (GenAI) with the debut of a low-cost but high-performance model that challenges the hegemony of OpenAI and other big-spending behemoths.

But several countries have questioned DeepSeek's handling of data, which the firm says is collected in "secure servers located in the People's Republic of China."

Nvidia high-end GPUs are in hot demand by tech giants building data centers to power artificial intelligence, and some say a low-cost option could weaken the Silicon Valley chip star's business.

Yurts co-founder and CEO Ben Van Roo, whose company specializes in keeping sensitive data protected while allowing access by AI models, believes DeepSeek's popularity bodes well for Nvidia.

"DeepSeek drastically accelerated the desire to consume these models," Van Roo told AFP.

"You've opened the world's appetite even more (to generative AI) and independent of the fact that it's Chinese, I think it was a good day for Nvidia."

- Blackwell Booming -

Nvidia has ramped up production of its top-of-the-line Blackwell processors for powering AI, logging billions in sales in its first quarter on the market.

"AI is advancing at light speed" and is setting the stage "for the next wave of AI to revolutionize the largest industries," Huang told financial analysts recently.

Huang believes Nvidia chips and software platforms will continue to power or train AI for robots, cars, and digital "agents," the term used for AI that can execute decisions instead of humans.

The CEO is also likely to talk up a leap to quantum computing.

After several dashed predictions, quantum computing is accelerating rapidly with actual use cases and scientific breakthroughs expected within years, not decades.

US tech giants, startups, banks, and pharmaceutical companies are pouring investments into this revolutionary technology.

GPUs like those made by Nvidia are ideal for handling multiple computing tasks simultaneously, making them well suited for quantum computing.

The US and China are racing ahead in quantum development, with Washington imposing export restrictions on the technology.

Nvidia reported that it finished last year with record high revenue of $130.5 billion, driven by demand for its chips to power artificial intelligence in data centers.

Nvidia projected revenue of $43 billion in the current fiscal quarter, topping analyst expectations.

How Safe Is Signal Messaging App Used by Trump Aides to Share War Plans?

Top Trump administration officials used messaging app Signal to share war plans and mistakenly included a journalist in the encrypted chat, spurring calls by Democratic lawmakers for a congressional investigation into the security breach.

Under US law, it can be a crime to mishandle, misuse or abuse classified information, though it is unclear whether those provisions might have been violated in this case.

Below are some of the main facts about Signal:

HOW SAFE IS IT?

Signal is an open-source and fully encrypted messaging service that runs on centralized servers maintained by Signal Messenger.

The only user data it stores on its servers are phone numbers, the date a user joined the service, and the last login information.

Users' contacts, chats and other communications are instead stored on the user's phone, with the possibility of setting the option to automatically delete conversations after a certain amount of time.

The company uses no ads or affiliate marketers, and doesn't track users' data, as stated on its website.

Signal also gives users the possibility to hide their phone number from others and use an additional safety number to verify the safety of their messages, it adds.

Signal does not use US government encryption or that of any other governments, and is not hosted on government servers.

The messaging app has a "stellar reputation and is widely used and trusted in the security community", said Rocky Cole, whose cybersecurity firm iVerify helps protect smartphone users from hackers.

"The risk of discussing highly sensitive national security information on Signal isn't so much that Signal itself is insecure," Cole added.

Actors who pose threats to nation states, he said, "have a demonstrated ability to remotely compromise the entire mobile phone itself. If the phone itself isn't secure, all the Signal messages on that device can be read."

HOW DOES SIGNAL WORK?

Signal is a secure messaging service that uses end-to-end encryption, meaning the service provider cannot access and read private conversations and calls from users on its app, therefore guaranteeing its users' privacy.

Signal's software is available across platforms, both on smartphones and computers, and enables messaging, voice and video calls. A telephone number is necessary to register and create an account.

Unlike other messaging apps, Signal does not track or store user data, and its code is publicly available, so security experts can verify how it works and ensure it remains safe.

Signal President Meredith Whittaker on Tuesday defended the app's security: "Signal is the gold standard in private comms."

She added in a post on X: "WhatsApp licenses Signal’s cryptography to protect message contents for consumer WhatsApp."

WHO FOUNDED SIGNAL?

Signal was founded in 2012 by entrepreneur Moxie Marlinspike and Whittaker, according to the company's website.

In February 2018, Marlinspike alongside WhatsApp co-founder Brian Acton started the non-profit Signal Foundation, which currently oversees the app.

Acton provided an initial funding of $50 million. Acton left WhatsApp in 2017 due to differences around the use of customer data and targeted advertising.

Signal is not tied to any major tech companies and will never be acquired by one, it says on its website.

WHO USES SIGNAL?

Widely used by privacy advocates and political activists, Signal has gone from an exotic messaging app used by dissidents to a whisper network for journalists and media, to a messaging tool for government agencies and organizations.

Signal saw "unprecedented" growth in 2021 after a disputed change in rival WhatsApp's privacy terms, as privacy advocates jumped off WhatsApp on fears users would have to share their data with both Facebook and Instagram.

Reuters lists Signal as one of the tools tipsters can use to share confidential news tips with its journalists, while noting that "no system is 100 percent secure".

Signal's community forum, an unofficial group which states that its administration is composed of Signal employees, also lists the European Commission as a user of the tool. In 2017, the US Senate Sergeant at Arms approved the use of Signal for Senate staff.

"Although Signal is widely regarded as offering very secure communications for consumers due to its end-to-end encryption and because it collects very little user data, it is hard to believe it is suitable for exchanging messages related to national security," said Ben Wood, chief analyst at CCS Insight - alluding to the breach involving top Trump aides discussing plans for military strikes on Yemeni Houthi militants.

Google's message services Google Messages and Google Allo, as well as Meta's Facebook Messenger and WhatsApp, use the Signal Protocol, according to Signal's website.
