Consider that as the article says, they don't currently have any kind of coherent address system at all. It's a vast improvement of the status quo.

Sure, this system doesn't make that much sense in a place like London or SF.

This remains a solved problem. The location phrase specifies the coarse location. Additional addressing information is used to introduce granularity. Look at how addresses are conventionally written already, and in a good chunk of the world, the addresses are written top to bottom, most specific to least specific. The largest remaining problem is that the location mapping depends on a proprietary database, but this is a common problem (in Canada the database of postal codes is also proprietary).

that's mostly true, except US/Canada we put the zip/postal code at the end which is more specific than the city/state/province. But your gist remains true.

True, but do note that postal codes and ZIP codes are a recent adoption, only deployed in US/UK/Canada since the 1960s

The history of post addresses is quite interesting in it's own right :)

Presumably this is handled by the software that is being licensed. Because if all the software does is do a conversion from words to gps coords, they're being taken for a ride.

I mention needing to resolve multiple addresses to consider them together. What further problems would there be?
