Sure, LN alone might not be enough to serve the daily transactions of billions of users. Still, it proves how layers built on top of the blockchain can improve the efficiency by several orders of magnitude with some reasonable trade-offs. LN is probably just the first of such layers.
Things like sidechains, cross-chain atomic swaps, various block space usage improvements (eg. Schnorr signatures) are also in the pipeline right now, all of which could further improve throughput.
So while LN may not be the silver bullet, it makes me hopeful that at least from a technical perspective, Bitcoin will be able to scale to become a global currency.
