the fact people still think you have to wait 10 minutes to buy a cup of coffee shows how early we are. Even Musk says Bitcoin isn't scaleable for twitter. Meanwhile with lightning there are apps that let you stream payments and there is a decent amount of activity here. Obviously it isn't at the scale of twitter but if twitter had their own lightning node (centralized I know) then you should be able to transfer at the speed of data.
