The usual "use cases" mentioned usually seem to boil down to:
- Acting as a lossy text decompressor (harmful)
- Acting as a lossy text compressor (mostly trying and failing to undo the damage from above)
- Acting as an outright bullshit generator (harmful)
- Acting as a poor substitute for a search engine with a propensity for trying to bullshit you (harmful)
- Acting as a poor substitute for a parser (which, even if it worked would be dumb because it doesn't understand structured output, so now you have two parsing problems)
- Generating broken and/or extremely poorly factored code (harmful)
- Hiding plagiarism (harmful)
GPT (and the AI hype in general) is the wrong solution to the wrong problem. Look at the effort that Google wasted on Duplex instead of OpenTable.
