> but this overestimates how much humans know especially with respect to space

Does it? We can't know how many secrets there are out there, maybe there's infinite and maybe there's nothing. It's hard for us to know the opportunity cost until we understand what we're bartering for.

Like, humanity could pool their resources to comprehensively explore the Mariana Trench if we wanted. That's fairly unknown, entirely feasible, and could yield scientific advancement. But it's also expensive, and doesn't guarantee any lucrative returns for us. Maybe there's gold deposits at the bottom of the floor, maybe it's all silt and sand. Maybe we harvest the gold, and discover that humanity has upset a delicate balance that has only survived by us ignoring it.

Iunno, if I was an alien civilization somewhere, I'd be praying to whatever higher powers exist to ensure humanity stays far, far away from me.
