Upon arriving at the facility, Bruce handed in his smartphone and passed through metal detectors. He was in awe of the semiconductor production line: Overhead rails carried wafers from one station to another while workers in white protective suits kept the machinery running. “It really just felt like I was touring some kind of living thing that was greater than humans; that was bigger than us,” Bruce recalled.

TSMC made attempts to bridge some of the cultural differences. After the American trainees asked to contact families and to listen to music at work, TSMC loosened the firewall on T phones to allow all staff access to Instagram, YouTube, and Spotify. Some Taiwanese workers attended a class on U.S. culture, where they learned that Americans responded better to encouragement rather than criticism, according to an engineer who attended the session.

Several former American employees said they were not against working longer hours, but only if the tasks were meaningful. “I’d ask my manager ‘What’s your top priority,’ he’d always say ‘Everything is a priority,’” said another ex-TSMC engineer. “So, so, so, many times I would work overtime getting stuff done only to find out it wasn’t needed.”

Training in Taiwan, which typically lasted one to two years, wasn’t all miserable, the Americans said. On the weekends, the trainees traveled across the island, marveling at the country’s highly efficient public transport network. Bruce spent his weekends hiking and frequenting nightclubs. He chatted with the families that run night-market food stalls, and entertained strangers who requested selfies with foreigners.

For the Taiwanese, many of whom planned for extended stays in Phoenix, that meant relocating entire families — toddlers and dogs included — to a foreign country. Many regarded it as a once-in-a-lifetime opportunity to explore the world, practice English, and send their children to American schools. Younger families planned pregnancies so they could give birth to American citizens. “If we are going to have children, of course we will have them here,” a Taiwanese engineer told Rest of World. “As an American citizen, they will have more options than others.”

Many experienced a culture shock. The bustling cities of Taiwan are densely packed and offer extensive public transport, ubiquitous street food, and 24-hour convenience stores every few blocks. In northern Phoenix, everyday life is impossible without a car, and East Asian faces are scarce

“Everything is so big in America,” said one engineer, recalling his first impression. He recounted his wife summarizing her impression of the U.S.: “Great mountains, great rivers, and great boredom.”

Having spent years under the company’s grueling management, they were used to long days, out-of-hours calls, and harsh treatment from their managers. In Taiwan, the pay and prestige were worth it, they told Rest of World — despite the challenges, many felt proud working for the island’s most prominent firm. It was the best job they could hope for.

Sometimes, the engineers said, staff would manipulate data from testing tools or wafers to please managers who had seemingly impossible expectations.

A former TSMC staffer who worked on the education program said managers were instructed not to yell at employees in public, or threaten to fire them without consulting human resources. “They would say, ‘Okay, okay, I get it. I’m not going to do that,’” the employee recalled to Rest of World. “But I think in the heat of the moment, they forgot, and they did do it.”

Chang-Tai Hsieh, an economics professor at the University of Chicago, told Rest of World that TSMC had found the U.S. a challenging environment to operate in because of the complicated regulatory process, strong construction unions, and a workforce less used to the long hours that are commonplace at TSMC in Taiwan.

Sitting in a room together, the engineers admitted that although they had made some progress in acclimating to life in the U.S., TSMC had yet to find a balance between the two work cultures. Some Taiwanese workers complained that management was being too accommodating in giving Americans less work, paying them high salaries, and letting them get off work early.

Some of the topics I touch on: Why I believe Vision Pro may be an over-engineered “devkit” The genius & audacity behind some of Apple’s hardware decisions Gaze & pinch is an incredible UI superpower and major industry ah-ha moment Why the Vision Pro software/content story is so dull and unimaginative Why most people won’t use Vision Pro for watching TV/movies Apple’s bet in immersive video is a total game-changer for live sports Why I returned my Vision Pro… and my Top 10 wishlist to reconsider Apple’s VR debut is the best thing that ever happened to Oculus/Meta My unsolicited product advice to Meta for Quest Pro 2 and beyond

Apple really played it safe in the design of this first VR product by over-engineering it. For starters, Vision Pro ships with more sensors than what’s likely necessary to deliver Apple’s intended experience. This is typical in a first-generation product that’s been under development for so many years. It makes Vision Pro start to feel like a devkit.

A sensor party: 6 tracking cameras, 2 passthrough cameras, 2 depth sensors(plus 4 eye-tracking cameras not shown)

it’s easy to understand two particularly important decisions Apple made for the Vision Pro launch: Designing an incredible in-store Vision Pro demo experience, with the primary goal of getting as many people as possible to experience the magic of VR through Apple’s lenses — most of whom have no intention to even consider a $4,000 purchase. The demo is only secondarily focused on actually selling Vision Pro headsets. Launching an iconic woven strap that photographs beautifully even though this strap simply isn’t comfortable enough for the vast majority of head shapes. It’s easy to conclude that this decision paid off because nearly every bit of media coverage (including and especially third-party reviews on YouTube) uses the woven strap despite the fact that it’s less comfortable than the dual loop strap that’s “hidden in the box”.

Apple’s relentless and uncompromising hardware insanity is largely what made it possible for such a high-res display to exist in a VR headset, and it’s clear that this product couldn’t possibly have launched much sooner than 2024 for one simple limiting factor — the maturity of micro-OLED displays plus the existence of power-efficient chipsets that can deliver the heavy compute required to drive this kind of display (i.e. the M2).

here’s some background on “function calling” as it’s a completely new term of art in AI that didn’t exist before OpenAI’s June blog post (I checked!). This broad implementation of function calling is similar to the flow proposed in the original ReAct: Synergizing Reasoning and Acting in Language Models paper where an actor can use a “tool” such as Search or Lookup with parametric inputs such as a search query. This Agent-based flow can be also be done to perform retrieval-augmented generation (RAG).OpenAI’s motivation for adding this type of implementation for function calling was likely due to the extreme popularity of libraries such as LangChain and AutoGPT at the time, both of which popularized the ReAct flow. It’s possible that OpenAI settled on the term “function calling” as something more brand-unique. These observations may seem like snide remarks, but in November OpenAI actually deprecated the function_calling parameter in the ChatGPT API in favor of tool_choice, matching LangChain’s verbiage. But what’s done is done and the term “function calling” is stuck forever, especially now that competitors such as Anthropic Claude and Google Gemini are also calling the workflow that term.

Apple’s M-series silicon team is simply on fire, doing some of the most impressive work in the history of computer architecture design and engineering. PC laptops in this class weigh over 6.5 pounds and offer terrible battery life; the 16-inch MacBook Pro weighs 4.7–4.8, the 14-inch MacBook Pro just 3.4–3.6, and all offer remarkably long battery life. It’s not like Apple’s silicon team had one breakthrough moment back in 2020 and have since been regressing to the mean — they continue to increase their lead over the rest of the industry in performance-per-watt.
