Gorn and Holodeck
Just had a thought wtaching SNW and wanted to share it. Wouldn't the Holodeck and replicator technology once again provide the opportunity to solve all problems with the Gorn. I'm aware it isn't fully available in the 23rd century, but: With the right replicator technology an ideal host for hatching Gorn eggs could easily be simulated.
Then Holodeck technology could be used to create the perfect breeding ground for the young Gorn without creating any friction with other intelligent species and maybe even tweak the conditions to be ideal for the young Gorn.
The main issue with them is, that the Gorn have to prey on others in order to successfully reproduce. With that technological solution, the biological imperatives involved would no longer necessitate aggression. Offering the Gorn the relevant technologies may be a way for the federation to solve their conflict with them and respect their culture and biology. Maybe that could be a reason why they are no longer an issue in the 24th century? Once the breeding is solved, adult Gorn appear to be fully rational individuals.
