He basically put it exactly how he intends: Like WeChat. An 'everything app'. Given that I am in China using WeChat every day, I can see the appeal from a business point of view.
I wake up and I go on WeChat to book a taxi to work. I go down and scan the white boxes where my breakfast was delivered using WeChat, and I grab a bottle of water from the vending machine on the way to the gate, paying with WeChat. During the Pandemic, I'd have to show my green QR code on WeChat to get out or in places. I pay the cab driver with WeChat, and when I get to work, after chatting to friends on WeChat, I communicate with my entire company via WeChat, no emails.
My girlfriend reminds me to book the flights for our holiday, on WeChat, as well as the Cinema tonight. When we get home, a notice on our door, we forgot to pay the bills. Nevermind - just go onto WeChat and pay.
I get home from work and fancy watching some livestreams. Maybe I'll give them little token monetary gifts - on WeChat. I'll check my friends picture updates (moments) and secretly cheat on my girlfriend* with the 'people nearby' function on WeChat. Maybe I'll buy some veggies on WeChat to make dinner tomorrow. But tomorrow is the weekend so we go play tennis, entering the courts by scanning with WeChat.
At the airport the next day we have to do a health check by scanning a code on WeChat before we can enter the departure gate. And on and on it goes.
Did I mention WeChat?
