What could possibly go wrong with powering up GLaDOS with all of NASA at her disposal? In a cunning ploy to cram our brains with knowledge, the Portal AI is teaching science to bumbling technicians.
It seems GLaDOS is moving up in the world from potato to Polaroid camera. It's an educational video to explain what fusion and fission is to those less scientifically literate, or fearful of AIs.
Valve's Portal series has already been used to teach kids about certain aspects of science, and it seems they're experimenting more with tongue-in-cheek videos.
CAUTION: Knowledge likely to increase - viewer discretion is advised. For science. You monster.
