This is from a dystopian anthology I read in the early 1970's.
Humans encounter a friendly alien race that shares advanced technologies. The protagonist's daughter (maybe) begs him to not use the Star Trek-style transporter. It seems harmless -- he uses it and so do most other people. Later they they learn the transporter kills off the person's creativity / spark / soul -- and that the alien culture has become insipid / barren from this effect.
This was NOT the Slabscape books (first published in 2010). I read this in the early 1970s.
