If the Chinese language is really such a notoriously difficult language to learn (and to speak) there ought to be no one using it anymore, right?
I dunno about you, but I do think
Actually, it is considered a notoriously difficult language for westerners to learn. I don't think that is hyperbole. "The hardest language and nearly impossible to learn" would be hyperbole. As someone who did learn Mandarin and spent a couple years in Asia speaking Mandarin with people on the streets pretty much all day every day, I can tell you it's about as different from English as you can get. Having also studied French, I can tell you it's much more difficult than picking up a Romance language. If you wanted to pick apart a section of the quoted text as inaccurate, it would be "particularly, to speak". You could pick apart the fact misplaced comma, or you could just look directly at his meaning. That implies that of the parts of learning the language, speaking is the most difficult. This couldn't be more wrong for Chinese. If you break language into four tasks: speaking, listening, reading and writing, then speaking is by far the easiest. Reading an writing in Chinese is something that most foreigners I met in Asia never even attempted.
There are plenty of people in the world who will maintain your vehicle for a reasonable price. Same with your computers.
Yes, and so long as you either 1) don't rely on your vehicle or 2) always schedule your vehicle's problems for times and locations where such a person is available, then relying on them is great. However, if you are driving on a freeway and have your car overheat in an area where there is no cellular coverage (I know there are a lot of urban dwellers here who will never visit a place without cell coverage, but I live in a more rural area where it's spotty at best), and you can't even locate the radiator cap, much less figure out how to add fluid, then you are SOL. Everyone should know how to do basic troubleshooting on anything that they rely on. If an item breaking down is just a minor inconvenience, then it's fine to rely on 9-5 service centers. However, if the item breaking down will seriously disrupt your life or business, then assuming it'll always just work when you need it and giving it no further thought is just reckless.
