Depending on protocols and ethics involved, he might be getting a databank of kryptonian DNA equivalents for the purpose of decanting them so either AI could raise them, and thus resurrect the civilization, or the AI backups could be downloaded into them and, thus, resurrect the civilization. Because kryptonians have technology for artificial gestation, and mental imprint AIs, so having a backup for civilization restoration in the form of either frozen cells or digitized DNAs makes sense.Edit 2: I'm just realizing now that Paul might be getting a full kryptonian medical database from Har-Zod. So he might be able to heal Match up right when he gets back to Earth.
Also possibly stuff like military tech database.
