From a internet dictionary:

redundancy /rɪˈdʌnd(ə)nsi/

noun the state of being not or no longer needed or useful. “the redundancy of 19th-century heavy plant machinery”

Ther are lots of things that are redundant. But why?

perhaps because most people don't like change ,that to stop using anything that is redundant would require a change. Or it is just habit and it's easier to continue with the habits than to change.

Or it could even be that rendunent things are being done with realising it. See 5 monkey principal
