It's not 20 and it's not 2. It's not a person. It's a tool. It can make a person 100x more effective at certain specific things. It can make them 50% less effective at other things. I think, for most people and most things, it might be like a 25% performance boost, amortized over all (impactful) projects and time, but nobody can hope to quantify that with any degree of credibility yet.

i'd like to think if it was really good, we would see product quality improve over time; iow less reported bugs, less support incidents, increased sign-ups etc, that could easily be quantified no?
