I've been dabbling recently, and as I've said before I'm quite put off by the limitations of Ethereum. As it stands now, it's main use case appears to be the development of new cryptocoins, perhaps voting applications..? And yet, every now and then you come across a nugget of true insight when working with the Ethereum protocol, for instance the gas payments to nodes to run code effectively should stop DDoS attacks since it would require vast sums of money to disrupt the network. It remains to be seen how valid this idea is in practice, but you could look at ideas like that and say, "Yeah, that seems like a step forward."

Anyways, if Ethereum really will become Web 3.0, then comparatively speaking I'd say we're not even in the 56k modem era yet.
