Welcome to Technology Daily, your go-to source for the biggest stories in tech, science, and innovation. It's April 21st, 2026, and we have a packed show for you today. Let's dive right in.

We're starting with the biggest story of the day, and honestly maybe the biggest Apple story in years. Tim Cook is stepping down as Apple's CEO on September 1st, after more than fifteen years leading the company. Taking his place will be John Ternus, Apple's current Senior Vice President of Hardware Engineering. Ternus has been at Apple for 25 years and has had a hand in shaping nearly every major Apple product you can think of — from the iPad to the MacBook to Apple Silicon. Cook, for his part, isn't disappearing entirely. He'll transition to the role of Executive Chairman on Apple's Board of Directors. The announcement was described as unanimous by Apple's Board, and Cook published a heartfelt community letter alongside it. Interestingly, Apple's official announcement didn't mention AI even once — a notable omission given the pressure the company faces in that space. Ternus is seen as a product-first leader, which marks a distinct shift from Cook's strengths in logistics and supply chain. Expect Ternus to be front and center at future Apple events. Apple is also reportedly planning to add thousands of employees as it reorganizes its hardware division into five key focus areas under new Chief Hardware Officer Johny Srouji.

Of course, this leadership change comes at a challenging time for Apple. The company could face a fine of up to 38 billion dollars from India's Competition Commission over alleged App Store anti-competitive practices. Apple hasn't submitted required financial data to regulators, and a final hearing is set for May 21st. And separately, the Mac Studio and next MacBook Pro could face release delays of several months due to a global memory shortage.

Switching gears to the space sector, we've got a mixed bag of news. Blue Origin's New Glenn rocket had a bittersweet outing during its third mission. The good news? Blue Origin successfully reused its first-stage booster for the very first time — a significant milestone. The bad news? The rocket's upper stage failed to place its satellite payload into the correct orbit. The satellite only reached about 95 miles up, when it needed to be at 285 miles to sustain operations. The FAA has grounded New Glenn while it investigates. This is particularly concerning because Blue Origin's next planned mission involves launching Amazon broadband satellites. Meanwhile, in other space news, the Artemis II commander Reid Wiseman shared a stunning video of Earth setting behind the Moon — the first time human eyes witnessed that phenomenon in 54 years, since the Apollo 17 mission. Wiseman captured the moment on an iPhone 17 Pro Max. And on the NASA front, questions are being raised about lunar spacesuit readiness, with NASA now relying on a single provider for this critical piece of its Moon mission architecture.

The SpaceX IPO is also looming large on the horizon. Depending on who you ask, it's either the investment opportunity of the decade or a massively overpriced gamble. Some estimates value the company at over one trillion dollars, which would make it one of the largest IPOs in history. Regular retail investors would be able to buy in for the first time. The central question remains: is there actually enough commercial revenue in space to justify that valuation?

Now let's talk about AI, because as always, there's a lot happening. Amazon has announced it will invest up to 25 billion dollars in AI company Anthropic — five billion upfront, with up to 20 billion more tied to performance milestones. Anthropic, in turn, has committed to spending over 100 billion dollars on Amazon Web Services over the next decade. This deepens what's already one of the most significant AI partnerships in the industry. Separately, Anthropic's new Mythos AI model is generating both excitement and concern. Cybersecurity experts warn it could dramatically accelerate hacking capabilities, potentially exposing vulnerabilities faster than they can be patched. On the government side, the NSA is reportedly using Mythos Preview, even as Anthropic remains locked in legal disputes with the Pentagon.

On a more consumer-facing note, Yelp is giving its AI chatbot assistant a major upgrade. The revamped Yelp Assistant can now answer questions, make restaurant reservations, order takeout, and book appointments through integrations with services like ZocDoc and Calendly — all within a single conversation. The chatbot now has a dedicated tab in the iOS and Android apps.

LinkedIn has also launched a feature called Crosscheck, currently in beta for Premium subscribers in the US, which lets users compare AI models from OpenAI, Anthropic, Google, and others in a blind taste test format. It's a clever way to engage professionals with the rapidly evolving AI landscape. And Google is expanding its Gemini integration in Chrome to more markets across Asia and the Pacific.

In a more troubling AI story, music streaming platform Deezer reports that 44 percent of its daily uploads are now AI-generated tracks — that's roughly 75,000 songs a day. While AI music represents only about one to three percent of actual streams and most are flagged as fraudulent and demonetized, the volume is staggering.

Researchers are also sounding alarms about AI-powered personas sophisticated enough to infiltrate online communities and subtly manipulate public opinion at scale — creating false consensus without detection. Scientists warn the next major election could be the true stress test for this technology.

Let's check in on the gaming and entertainment world. Nintendo has officially confirmed that Splatoon Raiders will launch on the Nintendo Switch 2 on July 23rd. It's the first spinoff in the beloved squid-shooting franchise, and while it's primarily a single-player experience, you can team up with up to three friends online or locally for raid missions. The game looks vibrant and action-packed, and yes — you can ride a manta ray into battle and apparently fire a shark at enemies. Sounds like classic Splatoon energy.

Apple TV Plus fans have something to look forward to as well. Silo is returning for its third and final season on July 3rd, with new episodes dropping every Friday through September 4th. Based on Hugh Howey's trilogy, the show has quietly become one of the best sci-fi series on streaming.

For gaming fans with a nostalgic streak, Ubisoft is officially unveiling the Assassin's Creed Black Flag remake — titled Black Flag Resynced — on April 23rd via a livestream. Rumors suggest it's a full top-to-bottom rebuild with a focus on pirate action and no modern-day sections. And looking further ahead, the Elden Ring movie is officially set for March 3rd, 2028, written and directed by Alex Garland and starring an impressive cast including Kit Connor, Ben Whishaw, and Nick Offerman.

In hardware news, AMD has released the Ryzen 9 9950X3D2 Dual Edition — a chip packing massive amounts of cache — for 899 dollars. Reviews suggest the practical benefits are there but limited, making it a tough sell for most users. Tesla, meanwhile, is expanding its Robotaxi service into Dallas and Houston, Texas, increasingly operating without human safety monitors in the vehicle. And robots are getting fast — a humanoid robot from Honor ran a half-marathon in Beijing in just over 50 minutes, beating the human world record by several minutes.

Finally, a couple of intriguing science stories. Scientists have discovered evidence of a bizarre new state of matter potentially hiding inside Uranus and Neptune — a so-called superionic phase where hydrogen atoms flow through a rigid carbon structure. This could help explain the mysterious magnetic fields of these ice giants. And researchers have developed a camera capable of capturing events unfolding in just one trillionth of a second, allowing scientists to watch plasma form and electrons move in real time.

That's your Technology Daily for April 21st, 2026. It's been a genuinely historic day with Apple's leadership transition, big moves in AI investment, space successes and setbacks, and fascinating science on the frontier. Thanks so much for tuning in.
