And LN still has a bigger learning curve than the layer 1 so, It is probably not going to happen any time soon.
Something like doge would work better than btc probably but again, it won't last forever because doge has its limitations too.
Ideally LN will be simpler to use than on-chain, sending transactions is already much simpler because you just have to paste the invoice, which can be done via QR code on mobile devices, so there's less room for error. Opening the channel is probably the hardest part, maybe in the future there will be specialized wallet software that makes it as easy as possible for non-technical people.
Not only Doge has limiations, like any altcoins it's much more volatile, so it's a really bad currency.
