That’s a very good addition. The old filters are still there and any one of them could still come back and bite us. However, when better technology becomes available, the older filters become less and less of a problem. Let’s take the bioweapons as an example. At the moment, we can develop cures and vaccines, but that technology has its limits. Perhaps one day our biotech is advanced enough that stopping a bioweapon from harming the citizens is as trivial as updating some software and changing a few passwords. Likewise, the climate catastrophe becomes less and less of an issue if the species is no longer bound to a single planet, but can also thrive in space.
