Other less measurable, but nonetheless actual result, is the increasing pace
at which "layer 2" solutions are developed (Lightning Network, Sidechain, Payment

An accelerated delivery is not always a good thing for development quality.
I'm more of the opinion that Bitcoin will succeed, provided that it does not fail, and that a misstep can easily be worse than doing nothing.
Intelligent people may disagree with this.
I agree.
Going too fast is never a wise thing to do, especially when you're dealing
with ~3.5bn system that could potentially bring a huge change in our society.
I don't know if doing nothing is the right thing to do, though.
I suppose that all depends on the definition of "success".
