Right now most jobs using ML do marketing or advertising. Fewer deal in image analysis, voice recognition or generation, or signal processing. But soon more jobs are likely to use ML to make mainstream apps, services, and tools more fault tolerant, adaptive, predictive, consistent performing, and automated.<p>I foresee uses for these new capabilities in communication services, IoT devices, user interfaces (esp language based), social communication tools, security, reliability, surveillance, and even some far out cutting edge stuff like personalization, GUI optimization, error correction, and restyling content and games and media to better match your likes and dislikes.
