Long term it looks like we all have to deal with colds, regular flu and now coronavirus too

So, the coronavirus looks like it's here to stay. However, I have a bunch of questions myself regarding all this. For example, "Does the coronavirus continue to kill humans at a 2% to 3% rate ongoing for 100 years into the future?" This would be my primary question. However, likely we don't have the answer to this question at least at this point. Also, a question might be: "Could this present virus be weaponized to kill at a higher rate and wouldn't terrorists or nations be tempted to do this?"

These would be my two most pressing questions worldwide in regard to this virus.
