I feel that nature has its purpose in wiping off certain species at certain times. This hasn't always been because of human intervention. Nature has always been putting species to extinction even in the prehistoric times.
I say let them be. It's nice to know about them and preserve them for as long as we can but to "resurrect" them may pose risks we're not yet aware of.
I share your opinion, I hope they develop the technology, and help other species, and do not end up like many movies show where everything goes wrong.
I appreciate your comment.
May you be very well.
