I’m British who now lives in Beijing, China. GB is more advanced than the US for sure technology-wise but compared to China, we are lagging far behind in terms of technology. I have not needed a wallet or paper money for the last five years. Whatever I need to do, I do it on my mobile phone. The UK is slowly getting to that stage for sure, my experience of the US is that they are at least 10 years behind. Honestly, I have been thankful that I got stuck in China since the pandemic, the embracing of technology has enabled people to have normal lives since May last year. The track and trace app system has allowed everyone to travel and use businesses safely. Very low infection and death rates, compared to almost every developed country.
