Up until recently I belive the majority of users of LN were from developing nations. For those populations already pushed to the brink, LN is a necessity.

I think nostr has been one of the first significantly effective pushes into the first world population. It provides them a wider more appealing use case for LN. Value4value/zaps resonate in the culture of the first world users. It's an evolution of the underlying psychological principles of why pokes/likes/👍🏽/❤️ are now standard social media functions.

This is only the tip of the iceberg though. Still a long way to go but nostr is the first of (hopefully) many other catalysts towards onboarding the world.
