Well, yes, it was amazing growth in 2017 and it would be even greater in 2018.
And yes, I can see a point in time where many of random witnesses with home grown infrastructure would no longer be able to keep up with the growth. And that's OK, because we are aiming at something bigger than just a proof of concept that bunch of geeks can run in their garage.
Scalability is and would be a challenge and a constant battle. The key is to keep an eye on your enemy, never ever underestimate it and plan ahead of time to avoid being ambushed.
If we can see some problem on a horizon it's great, because then we have a time to prepare ourselves and react accordingly.
I took a part in many discussions about scalability last week and I'm sure we can handle what is comming for the next few months.
And then?
By that time we will be ready things that we are not ready now.
And so on, and so on...
