technically speaking the existing emission mechanism could be smoothed out without changing the long term parameters, but it's not a neat exponential, flat percentage decay, it's some kind of power of 2 based logarithm

talking about the tail of it is pretty funny when you consider we are in the 5th epoch of halving, and there is 32

i seriously doubt that there will be the same denomination of 100M sats per bitcoin by a decade from now, the need for precision as the userbase increases is inevitable

Mises talks at some length about the difference between further increase of division of the denomination of a currency versus increasing the supply and concludes that you get a better net result in terms of incentives if you increase precision versus increasing supply (perverse fiat money spigot control problem).

i mean, lightning already has added a further 3 zeroes to the precision of bitcoin... when we reach dollar/sat parity i think everyone will agree it's time to add some bits to the denomination
