Hey Agata... I hope you will not turn us to some kind of experiment group, right?
Now time concepts differ throughout (pre)history, cultures and scope. The more one learns about them, it is easier to understand how past, current and perhaps future communities will prioritize tasks of any kind, and as a derivative "wasting time" will be constantly redefined.
Bitshares - OpenLedger and any other project built upon it, is a project that holds a lot of potential if handled correctly, I think.
Regards!
