I promise this question is asked in good faith. I do not currently see the point of generative AI and I want to understand why there's hype. There are ethical concerns but we'll ignore ethics for the question.
In creative works like writing or art, it feels soulless and poor quality. In programming at best it's a shortcut to avoid deeper learning, at worst it spits out garbage code that you spend more time debugging than if you had just written it by yourself.
When I see AI ads directed towards individuals the selling point is convenience. But I would feel robbed of the human experience using AI in place of human interaction.
So what's the point of it all?
Another point valid for GPTs is getting started on ideas and things, sorting out mind messes, getting useful data out of large amounts of clusterfucks of text, getting a general direction.
Current downsides are you cannot expect factual answers on topics it has no access to as it'll hallucinate on these without telling you, many GPT provides use your data so you cannot directly ask it sensitive topics, it'll forget datapoints if your conversation goes on too long.
As for image generation, it's still often stuck in the uncanny valley. Only animation topics benefit right now within the amateur realm. Cannot say how much GPTs are professionally used currently.
All of these are things you could certainly do yourself and often better/faster than an AI. But sometimes you just need a good enough solution and that's where GPTs shine more and more often. It's just another form of automation - if used for repetitive/stupid tasks, it's fine. Just don't expect it to just build you a piece of fully working bug-free software just by asking it. That's not how automation works. At least not to date.
