i don't have sound, so when i watched the video i don't know if there was someone explaining the output of the command line prompts, but from the video it looks like a grad student project, not a system to sell
Sound is definitely required for this video. And you're right, this is not something that's for sale. This video is effectively our "Hello, world!" We're optimistic about the technology, though, and look forward to showing off some really cool things in the near future.
