Only after using translation software will you come to realize how unreliable such tools are. Usually, such software is designed by developers who aren't native speakers so their logic is very different from that of native speakers. I have encountered this phenomenon many times. For example, when we say "you first!" in China, everyone understands what that means, but when you say it correctly in "after you!" some frown and consider that to be impolite. When I check that phrase with translation software, it always shows "you first". So, after making a lot of mistakes in the course of learning English, I won't learn anything about English from natives. I only subscribe to foreigner's channels to learn correct expressions or receive help from best friends like Pierre. He has given me a lot of help which I really appreciate. I consider any language in the world to be the most complex of tools. It takes us at least ten years to master with correct methods. Never rely on a piece of software. "Any language in the world is the most complex" doesn't make sense. Only one language can be the "most" complex. Maybe you mean to say "I think of each language in the world as a highly complex tool". I don't understand "when we say 'you first!' in China ... that's impolite". Are you saying that people speak English in China? I don't understand "So, after making a lot of mistakes in the course of learning English, I won't learn anything about English from natives." It seems to be the opposite of what you want to say. Don't you mean to say that you learn English best from natives?

Only after using translation software (software is uncountable), is it possible to realize how these tools are unreliable. Usually, translation software is invented by developers who aren't native speakers. So, their logic is very different from how native speakers think and I have seen this phenomenon many times. For example, when someone says " you first!" in China, everyone can understand what that means, but when you say "after you!" someone may consider that as impolite. When I type that phrase in a translation software, it always says: " you first". So, after making a lot of mistakes while learning English, I won't learn anything about English from natives. I only subscribe to foreigners' channels to learn correct expressions or to receive feedback from friends like Pierre, he helped me a lot and I really appreciate it. I think any language in the world is the most complex tool to use, it takes us at least ten years to master it with the correct method. As a conclusion, nobody should ever rely on a software to learn a foreign language.
