Everything and everyone is replaceable. There was that before and there will be that after, as if anything else was known.
Anything that is irreplaceable would lead to something forever broken, and at best something inideal. Somethings seem irreplaceable, due to the burden of replication or replacement, but at a point it will make sense.
It is sort of an ideal, however, to be irreplaceable: to be the expert, the glue, the monopoly. Though how nice to be that forever? Maybe a monopoly, yes, but nothing lasts forever. How unfortunate those under what temporarily irreplaceable.
All that is was once what will be. All is an attempt to fulfill want, want being a specific end to a need, or derivative to do so. Every item has substitute.
How many autocratic regimes in desperate times played the sweet siren of promised certainty? All is ours. Those that were gone, and those that will go, all will.
Then what? How trapped? At the mercy of whatever system of choice, or better yet, a predetermined luck!?
Though it’s a freedom, and simultaneously an attention earned. It means all is replaceable, but what is there is chosen.
It’s a greater meaning in a way. It was all guaranteed nothing would be earned. A game with unlimited currency and level, it all becomes nothing, and all fake anyways. But a game where one may lose, and often do, and most do, try on.
Best of luck to all those trying, and especially those not trying.
