The drive from central-ish Shanghai (Wujiaochang) to PVG was mindblowing because of the scale and frequency of the apartment megablocks ringing the city: identical enormous tower after identical enormous tower, lining the wide (but at the time oddly empty) thoroughfares. Felt like an alt opening scene to a Judge Dredd movie.
Some fun/awkward differences though. For instance, I had imagined it would be easy to find a laundromat - I didn't want to pay the hotel prices for cleaning. Ended up almost accidentally offending the people I was asking - "why would we need to go somewhere to do our laundry, we have laundry machines, we aren't poor" - while since a lot of US cities are older in the dense parts of town, laundry machines in-unit were less common even for sometimes pretty pricey places.
One of my big takeaways is that development is a lot easier and cheaper than redevelopment. Building a ton of new housing? Put in today's amenities! It might be crappy quality even in "luxury" new construction (whether here or there) but it's gonna be a lot easier than retrofitting into a bunch of units from 50 years ago. Want a QR-code/app-based payment system to take off? It's gonna be easier if you're one of the first widespread options to replace cash (like in China at the time) vs if you're competing with ubiquitous credit/debit cards in the US. Really illustrative of how things are path-dependent - and why I'm bearish on "super apps" replacing what we already have here.
In many (most?) European countries, debit cards and cash transfering apps are more common than credit-based payments. I have a credit card but I don't use it often (mostly for some online transactions, such as buying plane tickets), and many people only have a debit card.
That's the drukkhar architecture (we'll get to hear this word more often in the future). They are only missing giant grey flat-top pyramids: jusy as cold, efficient and brutalistic.
It's efficiency (fewer variants to make) + risk-minimization (design as a way of offending as few as possible for $$$ maximization instead of a way of expressing something).
The surface-level infrastructure was interesting, it felt like Los Angeles - much more than it did Manhattan or SF aboveground - just blown up 3-to-5x. Wider streets with more lanes of cars, big mega apartment complexes just all four times taller than the common 5-story ones, etc.
