It's just a matter of time before it does jump the species barrier to humans. We know from other such cases how disease spreads from butchered animals to human beings, from bats or infected cattle. Many pathogens can exist for years outside the contaminated source, and even exist in our bodies for years before deciding to become active. Many of us carry viruses than will trigger years down the road, and we don't know it yet.

So it's just really a matter of time before this happens. One thing we're good at as a species is, finding ways to make ourselves sick.

No, it's not just "a matter of time". While there are loads of pathogens that jumped to humans they were originally incompatible with, there are.myriads more that didn't and likely never will. The jump to humans is not a given.

Given infinite time, infinite possibilities present.

Quite literally, it IS only a matter of time, unless you are really good at standing in the corner with a bag over your head saying "nuh uh. Things that I dont like and that I am afraid of will never happen," in which case it still is only a matter of time, you are just ignorant and argumentative.

By this logic because there is infinite time and infinite possibilities, we could develop a cure or a virus that kills this prion and avert this crisis. We could also not and just die. Then there is a possibility that none of this exists and this is a simulation and the developers haven't added this as a feature yet.
