This observation is so important. There is unintendedly something being taken away from us that cannot be given back. And it's a pure loss, there is nothing returned to us on an experiental level. It already existed before that "somebody else" would solve or discover something. Now this "somebody" is just just an alien nobody can relate to. And that "something" is everything.
Even if AI solves ageing, and climate change and whatever else; as humans we'll have lost something beautiful and precious. There will just be less of this sense of wonder and curiosity.
