It definitely can. GPT-3 can too. You know the joke about "idea guy"? Who has "idea" but no programming/design skill and no connection to bring funding? New ideas aren't always very valuable.
At least GPT brings funding sometimes.
I'm finding it spectacular for generating ideas. Ask it for "40 ideas for plugins I could build for Datasette" for example. The results are comparable to what I've seen from a meeting room full of humans for an hour, but GPT-4 generated them in less than a minute.
Really? I feel like if you have to ask what plugins to build you’re doing it wrong. You should know what plugins to build by being a user of Datasette and understanding its limitations for your self.
I know Datasette better than anyone else, and I still couldn't come up with 40 useful ideas in less than a minute.
Once you have an AI to also prototype the plugin ideas, such an idea list may become useful. I've always seen that the owners of any product have more product improvement ideas than they could economically implement.
I asked GPT-4 to implement a simple plugin yesterday, and the code was 90% right out of the box.
