Something that irks me is the notion that the only science worthy of being conducted is that which has a direct practical application. I think if humans were omniscient enough to know what is useful, then we really would be past doing science.
The case which prompted this post: the reconstruction of a mummy larynx. True, it doesn’t directly help a living person. Plenty of people damage theirs in car accidents, falls, etc. By acquiring an 3D image of the person’s and building a replica, we could replace lost ones. And the person could have their same voice. Voice is part of identity given we recognize others by the sound of theirs. Mechanical replacements that sound inhuman are like wheelchairs: approximation, but the user still loses a lot.
Science and technology are collaborative endeavors. Others replicate a finding. They take an idea and do something similar but different to see if there were hidden variables that change the finding. Or, produce a product from the idea.
Too much focus on practical science is what led us to the Replication Crisis in psychology. People needing a useful result, meant not enough people replicating experiments to see if the results held. Mythical results went years without anyone publishing they were bunk.
