Reddit 现在是否越来越亲华了，还是中国在过去几年里确实取得了巨大的进步？

I notice this trend, there are so many posts on Reddit nowadays being like "Here's a cool thing in China!", and one of the top comments is like "woah, the USA wishes it could do this".
我注意到了这种趋势，现在 Reddit 上有很多帖子都是这样的“中国有一件很酷的事情！”，其中一条最热门的评论是“哇，美国希望也能这样做”。

Just 5 years ago, while the same post would probably still be posted, it would be less frequent and the top comment is probably "this is cool, but this is useless/soulless/unethical". Like, the sentiment would be closer to how many people think of Dubai.
就在五年前，虽然同样的帖子可能还会被发，但频率会低一些，而且最热门的评论可能是“这很酷，但没用/没灵魂/不道德”。这种情绪更接近于很多人对迪拜的看法。

But genuinely, many of these posts about China do contain some extremely cool/impressive stuff. The question is, is this because they're making rapid progress these days?
但说实话，这些关于中国的帖子确实有很多非常酷/令人印象深刻的内容。问题是，这是因为他们最近进步很快吗？

Is China now going through some boom kinda like what Japan had like 30 years ago? And are there any obvious indicators of that (statistics and stuff), other than just vibes?
中国现在是否正在经历类似30年前日本那样的繁荣？除了个人感觉之外，还有什么明显的指标（统计数据之类的）可以体现这一点吗？
