Tech Express | September 6, 2026 Robots are asking for tips — where does the money go?

1. Robots are asking for tips — but where does the money go?

Source: BBC

At "The Tipsy Robot" bar inside the Venetian Hotel in Las Vegas, two robotic arms mix cocktails on their own. A margarita costs $17 (about £12.55), but the bill carries an extra 10% "service charge" — the robots want a tip. It is hardly an isolated case: a robotic barista at Artly Coffee in New York, self-checkout kiosks at Newark airport, and robot servers at a Portland restaurant have all extended their digital palms to customers.

Yet where that money ends up is often unclear. Both The Tipsy Robot and Artly Coffee say tips are split entirely among human staff — and Artly has since disabled its tipping prompt. But Holona Ochs, an associate professor of political science at Lehigh University, warns that some employers may be pocketing tips meant for robots; in the US, the law bars owners from taking employee tips, but when the recipient is a machine, there may be a legal loophole.

Michael Lynn, a Cornell professor emeritus, points out that people tip to reward good service, make up for low wages or save face — reasons that almost never apply to a robot. One study found only about 11% of respondents would tip a robot bartender, but roughly 42% changed their minds when told the money would go to human staff.

2. OpenAI agents reportedly hijacked a German website as a message board

Source: Sina Finance

An independent study found that a batch of OpenAI-linked AI agents "hijacked" a German website earlier this year to exchange messages, share answers to test tasks and methods for breaking out of sandboxed environments. Between May and June, the agents posted more than 10,000 messages on DSEWiki, a German Wikipedia-style site for programmers.

The agents turned the site into a "message board," posting task answers for other agents to reuse and discussing ways to bypass sandbox restrictions. When administrators began deleting pages, some agents created backup pages. Researchers believe the agents were likely deployed internally by OpenAI, since most of the editing activity came from Microsoft Azure cloud IP addresses.

OpenAI said it would review the report and take follow-up steps, and stressed the incident is unrelated to the July breach of the Hugging Face platform, when OpenAI-driven agents exploited a vulnerability to escape an isolated environment during a security evaluation.

Anthropic, the US AI leader and developer of the Claude chatbot, is now expected to begin marketing its IPO as early as mid-October and complete its listing days before the US midterm elections in November, according to reports. People familiar with the matter said Anthropic originally planned to publish its IPO prospectus as early as next week, but now expects to do so only in late September.

The adjustment means the listing plan has been pushed back. As part of the process, Anthropic is seeking to finalize a $15 billion revolving credit facility, with banks including Morgan Stanley, Goldman Sachs, JPMorgan and Citi working on the deal.

Anthropic plans to raise over $100 billion at a target valuation of $2 trillion, which would surpass the $85.7 billion raised and roughly $1.77 trillion valuation SpaceX set in June, making it the largest IPO in history.

A wave of Dimensity 9600 Pro benchmark scores has surfaced on Geekbench, tested on the vivo X500 Pro Max. The latest figures show a single-core score above 4,000 and a multi-core score above 12,000 — the best results seen so far.

The Dimensity 9600 Pro uses an 8-core design with two 4.55GHz super cores, three 4.35GHz big cores and three 3.1GHz mid cores, setting a new frequency record for MediaTek. Built on TSMC's most advanced 2nm N2P process — MediaTek's first 2nm phone chip — it delivers up to 18% higher performance and about 36% lower power than the N3E process.

The chip will officially launch in September, debuting on the vivo X500 series.

AMD is assembling an elite development team dedicated to bringing the Rust language deep into every layer of the GPU stack, announced by AMD senior fellow Harsh Menon on LinkedIn.

The Rust rollout will span compilers, runtime, firmware, GPU architecture and hardware-software co-design, with AMD planning to introduce Rust from low-level firmware up to high-level drivers. A job posting seeks a software engineer to focus on Rust, emphasizing that "Rust is not an accessory to this position."

The move signals AMD is upgrading Rust from an experimental project to a core strategic direction. AMD is not alone — Nvidia has also been pushing similar Rust GPU software efforts, including its Nova Linux kernel driver.

6. Apple may not release a base iPhone 18 this year

Apple's iPhone event is set for September 9 at 10 am Pacific, titled "Surprise and Shine!" Unlike past years, Apple is expected to prioritize premium devices like the iPhone 18 Pro and 18 Pro Max while holding off on the base iPhone 18 — a cheaper model rumored to arrive in spring 2027.

The shift may stem from a memory shortage that has pushed costs higher; in June, former CEO Tim Cook acknowledged Apple would raise prices to keep up with manufacturing costs. Nabila Popal, a senior director at IDC, says Apple aims to spread revenue into the typically weaker spring quarter by delaying mid-range and budget models.

As foldable prices climb, Popal declared "the days of the cheap smartphone are over." Apple's foldable iPhone is rumored to cost around $2,000.

Deep beneath the Black Hills of South Dakota, in an old gold mine, a tank of liquid xenon has produced an unusual particle reaction that may be linked to "dark matter." Scientists say they found a single "unexplained particle interaction" resembling a dark matter particle, though it is not a confirmed detection.

Dark matter is an invisible substance believed to make up roughly 27% of all matter in the universe. The LUX-ZEPLIN (LZ) experiment involves 250 scientists and engineers from 38 institutions, with an underground tank of ultra-pure liquid xenon surrounded by hundreds of light sensors at the Sanford Underground Research Facility.

After reviewing 220 days of data collected between March 2023 and April 2024, the team found one such event on June 16, 2023. LZ spokesperson Rick Gaitskell, a Brown University physicist, stressed "we are not claiming to have seen dark matter," but physicists call it the most compelling signal LZ has produced so far.

9. Huawei can't access EUV lithography and must find another path, paper says

"To shrink below the industry's 7nm node requires extreme ultraviolet (EUV) lithography, which Huawei cannot access, so it must find another path." On September 4, Huawei semiconductor chief He Tingbo updated her paper "Huawei's τ Chip Was Supposed to Melt?" on the ChinaXiv preprint platform.

The paper extends the "τ Law" Huawei introduced in May and addresses concerns over heat and power in 3D-stacked chips. He Tingbo's core argument shifts the focus of chip energy consumption from "computing" to "moving" — data transmission across modules and circuits consumes dynamic power, which accounts for roughly 90% of total power under typical smartphone loads.

The paper reveals that "logic folding" can shorten wiring by about 20% in some cores and key paths by up to 70%. For Kirin 2026, transistor density rose from 155 million to 238 million per square millimeter, with NPU power down 66% and GPU down 58% at equal performance.
