This is like selecting the safe that you want to open, based on its mechanisms, interfaces, and capabilities. All the pros and cons are up against a single factor: time. We all are constantly struggling against time, the most precious resource, the one that gives meaning and importance to our actions.

This is somehow paradoxical; indeed there’s an eternal arms race between system makers and system breakers. Both have the same timeline but the value of their findings may distort the timeline and create somehow parallel and plausible scenarios until the patch would be released and many of these scenarios would collapse in the next software version.
