If you follow Chinese tech you should know what 卡脖子 or "neck choking" (anyone's got a better translation? seized by throat?) technologies mean. It's how the govt refers to high importance, high impact technologies that China relies on foreign vendors / countries for.

You'll hear investors & entrepreneurs use this term a lot as well. But what are these technologies? According to the Science & Tech Daily, they are as follows:

1. Lithography machine (Semis)
2. Chip (Semis)
3. Operating system (Software)
4. Aero engine nacelle (Aviation)

5. Tactile sensors (Manufacturing)
6. Vacuum vapor deposition machine (Consumer electronics)
7. Radio frequency devices for cell phones (Consumer electronics)
8. iCLIP technology (Pharma & Healthcare)
9. Heavy-duty gas turbine (Energy)
10. LIDAR (Autonomous Driving)

11. Airworthiness standards (Aviation)
12. High-end capacitor resistor (Consumer electronics)
13. Core industrial software (Software)
14. ITO target material (Manufacturing)
15. Core algorithm (Manufacturing)
16. Aerospace steel (Aviation)
17. Milling cutter (Railways & Roads)

18. High-end bearing steel (Manufacturing)
19. High-pressure piston pump (Manufacturing)
20. Aviation design software (Aviation)
21. Photoresistor (Semis)
22. High-pressure common rail system (Railway & Roads)
23. Transmission electron microscopy (Pharma & Healthcare)

24. Main bearing of roadheader (Railway & Roads)
25. Microspheres (Consumer electronics)
26. Underwater connector (Marine)
27. Key materials for fuel cells (Energy)
28. High-end welding power supply (Marine)
29. Lithium battery diaphragm (Energy)

30. Medical imaging equipment components (Pharma & Healthcare)
31. Ultra-precision polishing process (Manufacturing)
32. Epoxy resin (Manufacturing)
33. High strength stainless steel (Aviation)
34. Database management system (Software)

35. Scanning electron microscope (Research)

I did those loose categorizations, & in descending order they are:

7: Manufacturing
5: Aviation
4: Consumer Electronics
3: Semis; Energy; Railway & Roads; Software; Pharma & Healthcare
2: Marine
1: Autonomous Driving; Research

Anyways, the point was these "chokepoint" technologies give you a good idea of what people are going to be highly incentivized to work on and invest in. Also why Neil Shen said he was mega excited for the next few years for STEM grads. So much opportunity!

@petergyang

Thanks to @petergyang for alerting me to NFTs. It kind of reminds me of what Allen Zhang WeChat creator said a few wks ago on how he didn't believe that files would exist anymore in the future. The whole concept of files, making identical copies, = super outdated, in his opinion.

Instead of ownership tho, he thought of it from value to user. For the user, a lot of the value of an A/V file is now in 1) who's the creator, how can I easily discover other works? and 2) the interactions / community built around this content.

He didn't use blockchain to describe this, but it's a bit similar in principle. Content should just point to somewhere, and everything that happens around that content (the interactions) should become part of the content & accessible from everywhere, regardless of platform.

In case you missed the China GDP per capita report from 2020:

10 Cities $20K+: Shenzhen, Wuxi, Suzhou, Nanjing, Beijing, Shanghai, Guangzhou, Hangzhou, Wuhan, Ningbo.

3 are in Jiangsu province, 2 each in Guangdong & Zhejiang.

10 Cities $15-$20K: Changsha, Foshan, Nantong, Qingdao, Fuzhou, Hefei, Quanzhou, Dongguan, Zhengzhou, Jinan. Fujian and Guangdong provinces each have 2.

3 Cities $12.5-$15K: Chengdu, Xi'an, and Tianjin.

$10K+ considered "high income" cities. But only Chengdu & Xi'an are really in the "Western" part of China.

The eastern coast is still significantly richer than the western inland areas, but the latter is making progress, I suppose. Your thoughts?

How do Great Chinese PMs think? A🧵:

Besides Allen Zhang from WeChat, there are many other "super famous" PMs in China. One is YU Jun 1st Product VP at Baidu & then at Didi.

5 Aspects of Good Product Management:
1) Logic
2) Empathy
3) (Sector) Experience
4) Dissent
5) Data

The first 3 are more dependent on the PM & their life experience, what they did before. The last 2 is more on the company & how it organizes its systems.

1) On Logic:
You can be wrong on the conclusion, but you can't afford to be wrong on the logic (thought process).

2 diff types of logic:
Small Logic:
You are a food delivery co & it's raining. You prob need to add $ to your delivery cost.

Big Logic:
If you don't add $ even when it's raining, u lose some % but user might remember u & appreciate u, you'll get the next 5, 10 orders.

@joinClubhouse

On the @joinClubhouse town hall and @pdavison just mentioned tipping as a potential way of interaction. I mean I’ve always thought of it as Audio Livestreaming. Which led friends I to ask, why’s it not in China? Well it kind of is. YY has had audio Livestreaming function

since 2011 (too early? So early it was pc / discord style primarily used for gaming, not for phone, altho you could just audio chat like on clubhouse, and some eventually used it for education.) 1 yr old WeChat Channels video function allows viewers to send req to livestreaming

host to connect audio or video (as of Q4). So it’s there, and Allen Zhang seems big fan of it. Ximalaya (the audio book / podcasting platform) also has this function but it’s limited to 10 guest speakers. The issue w anything live in China is that you’re gonna have to do

@DanGrover

So @DanGrover & I going to record a recap on WeChat Channels, the 1 year old, 200mm DAU video / Livestreaming feature in app. It’s gonna be available on our @TechBuzzChina YouTube channel & you have a chance to post some Qs below that you think we should answer!

You can read things I've already written up (for our beta TBC Insider community) on WeChat Channels to get an idea of what we're going to cover minimally.

Here's a long recap:
insider.techbuzzchina.com/c/hot-topics/1…

And one of the most oft-asked questions right now, is WeChat Channels perhaps fundamentally different from Douyin / Kuaishou? Do they perhaps not even appeal to the same audience? Is it ... ahem ... for "old people"? Which BTW, is just 40+, so almost me!

Feeling so sad reading abt the tragic death of Gen Z Bilibili game streamer “Ink Tea.” Looks like he died of extreme poverty & lack of healthcare. His page now over 1mm fans (was 200 at death). W out his virtual friends crowdfunding $, he might’ve died earlier. Ppl still kind.

Current reports state his mom left at young age (divorce). Dad unreliable / ran from debt. He’s from a notoriously poor place in China. Even if his specific case untrue, can vouch personally w 1st hand exp that single parents v common in rural China. Lots of abandonment, disease.

Ppl so moved by his story bc despite being in pain not able to feed himself / buy meds he didn’t sell his story for pity $. Even tried to take care of a kitty, buy milk for it. Might be irrational but really understandable. Was a kid w no one else nearby. Hope the kitty made it.
