Earlier quoted context omitted.
Like with chickens, the Jayhawk should just learn to fuse hydrogen down to lithium. I think the analogy doesn’t quite work. Humans produce chickens because we can do that. We find more lithium because we need it. Jayhawks can also evolve to get better at finding more chickens. And by their very nature, have been doing exactly that.
Evolution is a bit slow. How many millenia will it take the Jayhawks to figure it out? Humans can increase chicken production this year or maybe next.
What I’m mainly pointing to is that we can’t currently just mass produce lithium. We just go around looking for it more.
