Loneliness breeds strange bedfellows. Rosetta Stone (played to a timorous “t” by Tilda Swinton), a bashful biogeneticist, downloads her own DNA into an experimental A.I. program, creating a trio of Self-Replicating Automatons (SRAs). Olive, Marine, and Ruby (Swinton3) live in seclusion in a color-coordinated condo where they spend their time Web-surfing, mainlining protein, and being inundated by motivational tapes that shape their sense of the “human.” Ensconced like priestesses in shimmering robes, the sisters SRA oscillate between machine superiority-“We're self-replicating”-and devolution-“When you are defensive and regressive you seem completely human.” Beyond their jacked-in consciousness, they yearn for attachments, but not the e-mail kind. Hershman Leeson (Conceiving Ada) has modified the gene for humor, creating a franken-farce wired for witticisms. Designed with sleek graphical interfaces, Teknolust bodes of a future when we will rise through “flesh, spirit” to “soul, icon.” Yet the film is also about something more fundamentally human-the impulse to fill the world with progeny as a gesture of existence.
