After all of those years in the lab, I can say that "I know that!" and mean it. And that I know what was being done to lay the grounds for a more effective compromise.

If you view the "triangle" of developer properties as flat, then by applying some new technology it can become effectively a "pyramid" bringing the points of the triangle closer in and making a developer that improves all 3 properties at once.
