LN fees will rise as the mempool gets saturated with LN channel opens, but I expect other Layer 2s and new Layer 3s will emerge further reducing on-chain pressure and enabling increased adoption at global scale.

This is a bit of a kluge, like the email to fax solution. Using a superior tech bolted onto an inferior one. Not the killer app that Bitcoin needs for mass adoption.

I am a bit obsessed with thinking about entrepreneurship that @car hinted at, that leverages Bitcoin for use cases that simply cannot be solved with the current financial rails. As a SoV, Bitcoin is wildy successful. As electronic cash, it's a solution still looking for a problem. Substituting Bitcoin gift cards for fiat or using a Bitcoin Visa card won't get us to the promised land.
