Chinese dialects are more different than you think. It's not just the same writing system with different sounds for each character. That seems to be a common misconception, and a very interesting one. But it's readily falsifiable.

• Here is the Mandarin wikipedia page on "software" - https://zh.wikipedia.org/wiki/...
• Here is the Cantonese one - https://zh-yue.wikipedia.org/w...
• And Min-Nan Chinese (a cousin of Taiwanese) - https://zh-min-nan.wikipedia.o...

If what you said were correct, there would only be a single page for all Chinese dialects. I suspect this misconception, which I once had myself, has roots in Chinese government propaganda, where the legitimacy of their power is more important than foreigners' understanding anything about China. I have a good friend, who is very intelligent and grew up in China, who says very passionately that "all Chinese dialects are the same language" and doesn't consider it up for discussion. Which is suspicious because it's equivocal and dogmatic at the same time; how many people know the exact difference between "dialect" and "language"?

My Chinese is terrible, but I do know the Mandarin word for "language" is yu3yan2. Replace "Chinese" with "Spanish" and you're more correct - "lengua" can mean either tongue or language.

It's also worth mentioning that LN enables sharding of the blockchain itself, since it enables atomic swapping of currencies. Let's say in the near future 1 million computers are willing to be a node (blockchain node, not LN node) for a cryptocurrency. If they all stored the same blockchain, that may be more redundancy and security than is necessary. So Bitcoin could fork into say 1000 separate blockchains (similar to Bitcoin Gold and Bitcoin Cash but on a much greater scale). Then 1000 blockchains each get replicated 1000 times. The LN can run on top of those blockchains to smooth out exchanges between the different currencies. Each individual user may only need to hold coins on a half-dozen currencies, the exchange and balancing of which are done automagically. This effectively means the settlement layer has greater capacity and can be used for smaller sums of money. Whereas with only one blockchain (Bitcoin) you may only close out a channel every year (or whatever frequency LN detractors have calculated), with 1000 currencies you could close out multiple times a day.
