The Future of Apple's Spotlight?

We're talking about highly advanced stuff here. It exists only in labs. So it's way too early to talk about specifics.

I don't want to blow anything out of proportion, but think of Spotlight as being kind of like the first bitmapped graphics. What we're doing with it right now is cool. But what's really important is what it enables us to do in the future.

GPS-based locational metadata is just one example. Automatic speech-to-text transcription for audio recordings is another. (You wouldn't believe what vector processing can do for speech-to-text. I saw a demo where a high-quality, noiseless audio recording of an unaccented speaker was transcribed at 20x real-time on a single 2.0 GHz G5.)

Example: You're doing a multi-party teleconference. A recording is made of that teleconference (each angle), and separate audio tracks are recorded for each participant. In real time, your computer transcribes each voice track and stores it as ancillary content on the recording, content that Spotlight indexes for you. At any time, you can type "meeting in San Jose" into Spotlight, and it'll take you right to the angle and track on which your co-worker Laurent talked about next week's meeting in San Jose.
