When you consider that a computer responds to instructions which predate its reading of them, it becomes clear that unless there is a code-break written into the programme doing the instructing, there will be no halting the run of that programme. In other words, be careful what you set in motion, there may be no way of slowing it.
Alarmingly, should the encoder neglect to use both foresight and hindsight – and fail to plan contingencies for virtually every conceivable problem that might crop up – there is little he or she can do but stand on the sidelines and watch if unforseen problems should arise and trip their systems. It is worse than infuriating for an IT sideliner when that happens, it tends to expose the glaring gaps in their actual understanding.
Technology is everything, and nothing. That is its power. Can you imagine the entire world wide web and its networks shutting down for a day? Just one day would wreak havoc on this capitalist planet. Not everywhere would feel it immediately, but the effects of such a shut-down would knock on, and on, like dominoes. There is a renewed respect that must be afforded technology when considering the grip it has on mankind.
