Here's your morning TNB Tech Minute for Wednesday, July 29th. I'm Imani Moise for the Wall Street Journal.
SK Hynix reported a record quarterly net profit today, and its stock fell nearly 10 percent. In just three months, the memory chip maker earned a net profit of about $64 billion. That's 13 times what they earned a year ago, and more than the company's combined net profit for the past five years. Yet the figure fell short of some bullish investor expectations, and fanned fears about the durability of the AI boom. The stock fell as much as 19.6 percent during trading hours in Asia before finishing down 9.6 percent. Shares and fellow South Korean chipmakers, Samsung Electronics, also fell.
Meta CEO Mark Zuckerberg said AI discourse should be more optimistic and warned against restricting access to the technology. In an opinion column for the journal, Zuckerberg said super intelligence or smarter than human AI will be, quote, the most profound technological advance we will see in our lifetimes. But he cautioned against its power being restricted to a select few institutions. Zuckerberg lends a high-profile accelerationist voice to America's debate over how to develop and regulate increasingly powerful AI models as his company races to catch up to rivals including Anthropic and OpenAI.
DoorDash plans to build its own aircraft and end-to-end aerial network. The San Francisco-based company has announced it secured a key certification from the Federal Aviation Administration to make commercial deliveries using drones. In addition to developing its own drones, the company is building out ground infrastructure and digital systems needed to coordinate order pickup and delivery. DoorDash has offered drone deliveries in some areas of the US for the past four years through deals with operators like Wing and Flytrex and said it plans to continue those partnerships. That's your TNB Tech Minute. We'll be back this afternoon with more.

Anthropics Claude is AI for problem solvers like JenSpark's Keju. Here's what this partnership means for him.

**SPEAKER_3** (2:21)
JenSpark is the all-in-one workspace. We do AI spreadsheet, AI slides, AI document, all kind of work for normal white-collar workers. We are a very small startup, so we cannot do everything by ourselves. Working with trusted partner is really, really important. In the collaboration, the openness is the key. The sum of the secret you kept today will be worthless tomorrow. The success of the partnership comes to deep mutual trust.
When it's really working, it's a very tight feedback loop.
