If I meet another founder who says “we moving at lightning speed and want to start production, immediately” I will jump into Shenzhen bay with a data server tied to my ankles, expeditiously 😒

I’ve been in Shenzhen for 7 years, working at Apple and small startups — but this is easily the coolest office space I’ve had ever had 😆

Coffee making robots working next to drone delivery stations The kind of stuff folks wrote about in scifi books is now just a casual Thursday in Shenzhen 😂 - craaaaaaaaazy

8 years ago I was a schwarzman scholar, sitting in this hall + listening to legends divulge china knowledge accrued over decades Last week, I got to return to the same hall and share my 7 years in shenzhen - teaching folks how to build hardware from zero to one Just grateful!

last year, I asked a bar if i could borrow their space once a month; started this event with only 15 attendees- a year later, tech in the tropics has 60+ monthly attendees ; standing room only! founders from all over the world coming for brews and convos! feeling grateful atm 😂

Work-life balance has been COOKED the last 4 months. • replaced a co-founder, hired 2 staff • led Saudis thru factories on Christmas • drove 8 hours to CES after Frontier killed my flight • back to China for 3 QC inspections • rush ordered AI product PCBs All before CNY.

This is the cost of freedom tho— Freedom to choose the projects I execute. Freedom to choose the people I build with. Freedom to shape the brand and legacy this all leaves behind. Freedom to experience summertime Chi and wintertime Shenzhen 😍 I’ll pay this cost every time.

Recently, I gave a keynote, and a student came up after like: “Hey, I know you from Red Note! You made a video about an engineering book — I bought it and now I’m building products.” Bro then asked me to sign the book I didn’t even write 😭 Keep creating. Someone’s watching.

🧠 Tech in the Tropics #8: Unlocking the Mind Can wearable tech tune your brain for better sleep & wellness? 😴 Next week, I’m hosting Emma Zhang, CEO of Vibe Science, to talk about Synthia — a wearable blending neuroscience, AI & design 🔥 DM to RSVP #Neurotech #AIHardware

We keep funding AI to “optimize” production, but the real bottleneck is human: no one remembers how to build anymore. MIT’s FReD Lab wants to fix that — by teaching the next gen process control, computer vision, and statistical process control — pro level skills here!! 🏭

In the 90s, reporters went on TV asking if [@] was pronounced “at” or “about” 🤣 Feels just like today with AI — everyone asking what it is + how to use it. We all should keep up with the new tools — don’t want Gen Alpha laughing at us in 2040 😮‍💨 youtube.com/watch?v=UlJku_CS…

🤖 Being back in the Chi feels like walking through my personal museum — found some relics from my MIT MechE days, including my 2.007 robot… basically a duct-taped mess of aluminum plates, servos & PCBs 😂 (🧵1/3)

🪀 The next year was 2.008, where things got real: CNC, injection molding, thermoforming, lathes, DFM/DFA. We went from making coins & flashlights to mass-producing yo-yos in 10–15 person teams. Our team made a piggy-bank yo-yo 🐷💰 (🧵2/3)

Could China’s new K visa make Shenzhen the launchpad for the next wave of global startups, while the US keeps pushing talent away? 🤔 IDK… but I’m bullish on it 🤣 ✈️ First came the visa-free transit scheme — a few days in China if you’re en route to a 3rd country. (🧵1/3)

Now… the K visa. And honestly? This one’s a big deal: 🎓 Targets young STEM talent 🔄 flexible re-entry 📝 No employer/school invitation required For tech folk, this means: 🌏 Career experience in China ⚙️ Flexible manufacturing/tech partnerships (🧵2/3)

🌏 Living abroad will change you… And you may not realize how much—until you are nearly booted from a downtown LA AT&T store 😂 May 2023 was my first time back after 3.5 years in 🇨🇳. Landed, reunited with the bros… and was weirdly happy to see pickup trucks lol (🧵1/4)

📶 I didn’t have a US number, so I dragged a friend to the nearest AT&T. Everything’s OK until I realize I’ve walked behind the counter, phone in hand, holding it up inches from the worker’s face, asking for a new SIM 😅 In my mind: completely normal. In LA: not okay. (🧵2/4)

🎶 “Do you think about me now and then… I’m coming home again!” That old Kanye track been looping in my head the whole Hong Kong ➡️ Chicago flight 😮‍💨 Complicated legacy, I know — but he did write the soundtrack to my Chi-town adolescence… and the nostalgia hits hard. (🧵1/3)

I’m back in the U.S. for the next 5 weeks: 📍 Boston (this weekend) 📍 NYC (next week) 📍 Chicago + SF (later on) If you wanna meet up, grab coffee, or hear about life in the land of factories and humidity — hit me up! (🧵2/3)

🎭 One of my fav sayings in Chinese goes: “外行看热闹,内行看门道” Roughly: “The untrained eye enjoys the show. The expert analyzes the mechanics.” Whether it’s theater or hardware manufacturing, I’ve seen that truth firsthand… (🧵1/6)

In 2023, I visited Guangzhou to watch “INSANITY” — a modern Chinese adaptation of One Flew Over the Cuckoo’s Nest with sci-fi, dystopian flavor. As a total layman, I thought it was DOPE: • dramatic lighting • cool character types • and a wicked plot twist at the end (🧵2/6)

If you ever spot me in the Shenzhen wild — at a factory or in the markets — chances are my outfit will raise a few eyebrows 😜 Here’s the thing: Shenzhen, despite all its futuristic hardware chops, is basically a 20+ million person sauna. Sweltering. Humid. Relentless. (🧵1/7)

So I’ve made a few personal policies. 🧥 Long sleeves? Nope! 👕 Short sleeves? Only on laundry day. 🧢 Tank top season? All year round! I’ve got 10 years dreadlocks, and hail from a city where we canceled school for wind frostbite warnings. So 91°F + 100% humidity? NOPE! (🧵2/7)

🐎 Recently visited one of the largest copper manufacturers in the world And somehow ended up at a horse-riding stable for grade schoolers?? 😭 Here’s what happened on our trip to Hailiang Group — a $30B Chinese copper giant with way more up its sleeve than you’d expect… (🧵1/8)

🏭 Hailiang started as a small copper tube operation in 1989. Today? They control 30%+ of the global copper rod market and operate factories in 13 countries — including Texas and the Midwest. They even moved into Southeast Asia in 2005, way before it was trendy 👀 (🧵2/8)

😩 I didn’t start a company to write invoices, proposals, or organize contacts. Luckily, Lindy.ai is doing most of it for me now 🙏 Been playing with a ton of AI tools lately, but Lindy’s my new favorite company co-pilot handling a lot: (🧵1/6)

📇 Contact DB Management Pulls info from Gmail threads, adds company bios, LinkedIns, and public intel. No more “who TF is this?” moments when I’m reviewing leads 😂 🧾 Invoice Generation Based on chat context + templates, it whips up ready-to-send invoices in seconds. (🧵2/6)

“China is one of the most capitalist, consumerist places on Earth.” I said that—on record—and @BusinessInsider published it verbatim 😂💀
 High-school me was the kid reading BI to decode the world. Present-day me just woke up to a profile in the very same place 😳 (🧵1/4)

Honestly thought they’d sanitize the spicy bits… nope. They kept the “China capitalism” line in. Though, I stand by it. Thirty-plus years of hyper-growth + 86 M people hustling in the GBA = capitalism on rocket fuel. (🧵2/4)

📍Shenzhen > Silicon Valley? Maybe not today… but give it 10 years. Why I’m building in China’s south—and why more global founders may follow 👇🏾 (🧵1/6)

📦 The Greater Bay Area (GBA) is China’s megaregional play: 🇭🇰 Hong Kong = finance 🇲🇴 Macau = tourism & trade 🇨🇳 Guangdong = deep manufacturing powerhouses like Shenzhen & Dongguan This region has 86M+ people and a GDP >$2T—already ahead of Canada and South Korea. (🧵2/6)
