In some cultures,correcting someone older than you is frowned upon.But the truth is we all have been doing it since the beginning of life.How do you think we got till here? By adhering to the norms left behind for us? By sticking to half-built technology that didn’t satisfy everyone? What was evolution then? We are constantly correcting or if you would like to say ‘modifying’ what was left behind for us by our ancestors because it is either wrong or imperfect.The world changes and thus our thoughts & needs.
So don’t think too much when correcting a senior (do it privately and verrryyy subtly).They don’t necessarily have to be dead or far away out of earshot to be corrected.Everytime you hold yourself back,you might be holding back an innovation that could make your life very easy.At least think about your own benefit?
