I just browsed the Movies folder of the game file, and looked into the Techs.

Interesting names for the bik movies. We have things like these:
Terrorstar0.bik
Terraform0.bik
Viruselim0.bik

I have played a few Large Maps as the awesome N-1 (Yor) and never came across these texts. The feeling in my guts tell me that these super-techs require super technology and super luck to achieve. Has anyone ever managed to construct a terrorstar or eliminate viruses from their systems??
