Besides that you are right; especially things they do better; they have Facebook but the messenger (Wechat) is really were it is at; I use Wechat now instead of Messenger and it is superior even when you are not in China. Mainly because it just always 'works' and it's always fast unlike Messenger. Didi is better than Uber in many ways especially for the Chinese; for foreigners it's fine but Uber is more convenient for us as support is in English and most drivers for Uber speak a bit (enough) of English in China while the Didi ones speak no English at all usually.
In my experience, wechat is a spam monster - too many useless notifications and missing useful features like easy OTT voice calls and read receipts. I find iMessage and whatsapp (I use both hourly) vastly superior.
How old is your uber/didi experience? I find both now to be mostly useless to non-chinese. I tried to get an uber to the airport in Beijing last week and would you believe there is no POI in english for "airport". Search comes up empty. This seems recent, it wasn't an issue last year when I was travelling there frequently. I agree, if you do get a valid destination the uberx drivers have enough english to find you and get you where you are going. People's uber on the other hand... its good for entertainment...
The taxi queue at BJS is quite reasonable most of the time, so I don't bother with didi.
But this is why doing biz can be hard in China, so many business models operate in grey zones while the government lets them go on while swinging a huge axe over their head. As another example, did you know electric tricycles are illegal throughout the entire country? And China's whole new goods delivery businesses are built around these....
Didi is great if you can speak a bit of Chinese. I've had a decade of perfecting my taxi driver Chinese though (since I seem to only use Chinese to talk to taxi drivers these days). YouTube is still way better than youku/tudou for content discovery...they have no "popular now" for non Chinese content.
I also resent not being able to use google at home, so I like using it at work.
For dev results or? Because that's simply not true. Try finding things like knitting/wool shops in Shanghai on the Chinese Bing and on Google. You won't be getting any knitting done if you use Bing; all the hits you get there are closed many many years ago. There are many other examples from daily life which we encounter when in China; we're going there in a few weeks again and i'll jot down the differences then; there is an awful lot which you simply cannot find in Bing while it's in the top hits in Google. We might search for different things but 'hard to tell the difference' is really just weird to say.
The weather is also pretty nice in the South Bay (over 300 days of sunshine according to Wikipedia for San Jose). San Francisco technically gets a lot of sun, but anecdotally they get a lot of fog and shade as well, especially in certain areas of the city. There are other benefits to Left Coast living as well, but the rent is indeed high.
Please don't do that.
