They probably aren’t. But they are qualified to comment on a theoretical post about the subject.
OP is asking what each person would contribute, not that each person must contribute something that they are qualified to. Which, for the most of us, is nothing.

I guess I misunderstood the question as being what we we’re capable of personally contributing.
If it’s just hypotheticals, I would contribute antibiotics and how to make those.
