Zero shot classification on any random task seems like a pretty huge deal to me.
Copilot seems like a pretty clear use case that is very useful, Copilot is currently writing 10-20% of my code, sometimes more, sometimes I don't even have to read the docs or go on stackoverfow, for example I didn't know much about AWS S3, started writing a class with copilot, and autopilot +/- autocompleted a whole 150 line file, the only thing it got wrong was an uppercase in a table name(which wasn't mentioned anywhere and that it just guessed!!)
Automated description of pictures, seems like it would be pretty useful to blind people once it can be done reliably in +/- real time/on video.
I've been thinking about using GPT or Bloom to take my job search automation to the next level:
filter companies that match my criteria(using more than simple metrics that can filtered with regular code), for example I want companies that works against climate change, with good remote policies/remote first, a focus on code quality, I want to avoid certain technologies etc...
generate cover letters by using the job description+data about the company+a summary of my resume(or even the recruiter profile) as input
If you think it have no use cases you just have no imagination
