I really appreciate your taking the time to create this sort of series. Periodically there will be heated arguments about steemit's scalability and the technical requirements for running a node, and I find myself pretty uninformed as a reader.

This fills in some of the gaps and I imagine future posts in the series will fill out more.

But I am interested in your opinion about scalability. There was a ton of growth in 2017 - and presumably that growth wil continue, as you anticipate. But does their come a point where the growth is no longer scalable for decentralized volunteer witnesses to handle? I imagine the amount of information being transacted through the blockchain in 2020 would still be nothing to, say, a Google server farm. But will it be manageable by witnesses at the current rate of growth?

(I'm really just curious - I'm not coming at this question with any pre-suppositions or hypothesis - end of the day, ima just keep plugging away at my fungal hobbies regardless - but this scalability question is a point of interest nonetheless, and as it comes up periodically in high level comment threads I'd be interested to hear your opinion.)

Thanks for all you do!
