You are on a site hosted in that backwards country, funded by people from that backwards country, using technology initially developed by that backwards country, on a thread about new SOTA technology originating from that backwards country, almost certainly using software and hardware from that backwards country to spout offensive things about that backwards country.

Maybe the US isn't as backwards as you might believe, or maybe Airbus is a backwards company for using feet and knots? Perhaps different measurement systems have their virtues (give me an exact integer representation of 1/3 of a meter. For a foot it is 4 inches. For a yard it is 1 foot or 12 inches.)

For the record, the US made the metric system the preferred system of measurement 50 years ago. So you are also uninformed in your attempted insult about US exports (1975, Metric Conversion Act). Americans also learn about the metric system in school, and are more than capable of using it when it matters (the American weapons that Europe and Ukraine seem so fond of use the metric system).

I don't live in the US, but I have lived there in the past, and making sweeping insults about 400 million people is something I learned not to do.
