# Some of the *Blade Runner* technologies that have come to fruition by 2019 include:

 - Giant electronic billboards that show full motion video ads.
 - Crosswalk **Walk/Don’t Walk** indicators that include audio prompts for the visually-impaired.
 - Self-driving cars (**borderline**).
 - Access to police databases from in-car computer.
 - Voice-interactive computing (but **not** magical photo enhancement).
 - Electronically dimming windows.
 - Some aspects of gene engineering and creation of artificial animals (for example, a rat kidney has been 3D printed from stem cells; this is perhaps also **borderline**).
 - Video phones.
