Why do we so readily convince ourselves against doing the right thing, picking good technology? "Over engineering" is a huge massive bat of a word that is applied to "correct" all kinds of spirited ambition.
Fear Uncertainty & Doubt is a dangerous default mode to adapt. I do not feel that it should be such an ordeal, require such courage, to do the good & right things. Better to try & fail than risk whiling ones time on lukewarm efforts.
What is the actual danger here? What are you afraid of? Why hold your biases against another's endeavor?
