I'm still curious if SMTs will see the light of day any time soon. We don't really know how they will play out in detail... they might be changing some paradigms... they might wreak havoc on this already bloating chain. Who knows?! We'll see! But I agree it might be a game changer.
Apart from that, the issue of STEEM feels "deeper than that". I think the rampant abuse of vested stake under "money-printing-mentality" and circle-scams that do cause the biggest downwards pressure... I can see where that may get even worse with SMTs in the mix but maybe I'm just paranoid.
