Sometime during the 80's, Cave Johnson had renamed the company Aperture Laboratories, a name that would be known far into the future.

The technology has advanced greatly, where robots are beginning to replace human employees. Said employees then become unfortunate victims of science in Cave's visions of the future of science.
