An "everything" app like WeChat doesn't make sense in America. Uber Eats is about as close to an "everything" app considering it now has the scale to order literal stationery from Staples or CVS in addition to overpriced junk food. Cost is the limiting factor. @AltisticRight is a better person to talk about this, but transaction fees in China are comparatively cheap relative to America. What impetus is there for Meta to go all-in on the "everything" app paradigm between Facebook, Instagram, and WhatsApp in America, when payment processor fees will eat into their profits and everyone's charging their own markup to offset their losses? WeChat is the undisputed titan of China, but other apps like Alibaba, RedNote and Douyin have similar marketplace or even payment processor features, Even if we try doing 1:1, other companies will scramble to scale upward for diminishing returns.
