I lack imagination. What is GPT-3 (and generative text models in general) useful for, other than toys? It can write essays, can we expect it to replace writers for newspapers and magazines? Can it write coherent technical documentation? Replace speechwriters? Edit: looks like the comment thread below is similar https://news.ycombinator.com/item?id=32554955
It will aid speechwriters or help more people write their own speeches, I guess.
Assuming that AI tech is a person replacement is, IMO, the wrong mental model. It helps talented people be more efficient. And will help a lot of hacks “fake it till they make it.” Power to the people, if they can handle it.
