Fair enough. I can see your point about engineering, but in this case I find it hard to classify the generic SaaS programmer and the guy calculating Pi to 2700 billion digits on his workstation using his own formula - which actually is the innovation here - under the same rubric, but I guess that boat has sailed a long time ago.
Odd example given the SaaS programmer might be doing actual engineering but the math calculation is not engineering by definition. Which is not to say the latter is not more impressive.
