13700k seems to be similarly priced now compared to 7900x.
AMD slashed prices due to poor sales of zen4, 7700x used to be more aligned to 13700k pricing than 13600k. Before that Intel was actually usually the better choice between the two.
That’s not really how currencies work. They are not just something arbitrary, they are a thing people trade which has value formed by supply and demand. People buy dollars to be able to buy things that are sold in dollars. Same goes for other currencies.
What would be the demand for UN currency? What can you buy with it? How would the price be determined?
The idea that USA somehow hugely benefits from having so much international trade done in dollars is also a bit weak. It does give them some international clout but that’s about it. There are some very complicated things relating to trade balances involved when your currency is the global reserve currency.
In this case it really seems this windows convention is bad though. It is uninformative. And abbreviations mandate understanding more file extensions for no good reason. And I say this as primarily a windows user. Hiding file extensions was always a bad idea. It tries to make a simple reduced UI in a place where simple UI is not desirable. If you want a lean UI you should not be handling files directly in the first place.
Example.zip from the other comment is not a compressed .exe file, it’s a compressed archive containing the exe file and some metadata. Windows standard tools would be in real trouble trying to understand unarchived compressed files many programs might want to use for logging or other data dumps. And that means a lot of software use their own custom extensions that neither the system nor the user knows what to do with without the original software. Using standard system tools and conventions is generally preferable.
