Yes, this was what I was trying to convey. Customers (when I ran my company) explained it to me in terms of Moore's law. They could wait 5 years for 1 order of magnitude (back then). Or I could deliver that (near) order of magnitude now, but the economics still had to work out. So kN where this was not tremendously different in TCO than existing solutions.

kN might be 1.25x existing costs for 5x performance today. This was an actual example given to me. Customer then indicated that they'd be quite interested in performance at that price.

k*N >> 2x, and it got problematic. So I had my range to work with.
