A pragmatic approach used by many people is to say that, since we’re talking about a paradigm shif, the calculation of ROI can’t be done according to our current thinking processes and deserves an empiric approach.

So let’s have a look at a good old methodology that no one could disagree with.
• Archimedes found the so cold theorem while having a bath.
• Isaac Newton made a major discovery while sitting under an apple tree from which a fruit felt right on his head.
In both cases, formalization came from experience.
