We already do use them

I know a guy with a lightning ⚡️ routing node and he says he gets payments in msats all the time on small transactions

So it’s already a thing in lightning

Not someday

That shit is happening now

lol

I zapped someone 2 sats from olas

Or what I thought was 2 sats

And when I clicked on the tx in my wallet it said I sent 2,000 msats
