The world isn't magic. If there is a catch or let us say a 50% discount in using LN for Samsung phone payments, I am sure even those who do not know it will try to understand what LN is just to avail of that 50% discount. There should be a driving factor for people to use LN without it, they will just use fiat payment since it is more convenient to just swipe a card than create/join a channel for LN payment.
I didn't say there will be a discount but I did say to put apps that use LN inside our smartphones. Take Uber why pay only with cards and not LN or again airbnb, eBay, amazon all these are apps that could potentially use LN (obviously they won't for now) but if someone is developing an app that uses a payment then put LN in the your app. You don't necessarily have to open channels or self-host a node but also use custodial wallets and send almost instantly or onchain or exchange in your own currency but in this way you will still have fed the network and incentivized the developers through fees. Don't always be hostile to change, don't think it's always wasted energy.
That would be very effective if the only option of payment is LN. It would be not as effective as you think if there is some other option of payment which is more user-friendly and more convenient to use. Besides if we develop an application for payment, isn't it easier to just have an internal transaction than using LN network? The app's feature itself then possibly kills the purpose of LN transfers since more probably than not, users will use the convenience of internal transfer. This is not different from an application that has an internal transfer and an integrated bank transfer. Most users avail of the internal transfer because it is cheaper(no fee in most applications) and faster.
You say this because you most likely live in the first industrialized world where everyone relies on their bank to keep their assets and obviously have a MasterCard in their pockets. Now expand your mind and turn the world map, catapulted into Africa where 90% of the population is Unbanked but will most likely have a smartphone in hand, give it the opportunity to buy something without transition costs without any bank account and in the blink of an eye take a look and tell me if it can work.
axctually you do need to improve it
el salvador tried it and seen how broke it wasn. and yep within 3 months they stopped using LN as the behind the scenes system of chivo..
lol you probably don't know what you're talking about, in El Salvador it's not LN that doesn't work but just the adoption of how it was dealt with. So I avoid commenting more because you're basing your speech on a concept that doesn't hold up. Instead try checking out Bitcoin Lake or Bitcoin Jungle to see if that works.
