Most creatives that use AI don't use it as a replacement. They incorporate AI into their artistic work and use it as another material or tool.

As for getting technology to do almost everything for us, I guess it's different if someone is just using an AI versus someone who is making an AI. I'm planning to use AI input in one of my creative projects and I'm working on making an AI program now and it isn't the easiest thing to do. There's a lot of learning and problem solving involved in programming things you have never programmed before.

I personally love AI and find it fascinating so I work with it for some of my creative work (not all of it though because not all of my creative stuff is something that AI really fits into). I think it would be sad if AI writing was the norm and the reason that was the case wasn't to explore how it is developing but was simply for convenience, but as an area to explore and use for artistic purposes it's quite interesting.

AI writing on a large scale (ie writing a novel etc) doesn't seem to be there yet from the examples I've seen, like this:

but some of the smaller things have been somewhat believable and not been complete nonsense, at least not all the time (ie tweet bots etc).

You can see in the Harry Potter thing that it has found connections between words ie connecting Ron with spiders, but it just hasn't quite got it worked out. I imagine getting an AI to write an understandable would be very hard and have to involve a lot of data and a lot of training though, so this is completely understandable. Right now it's just funny.

People don't necessarily want smart AI either though. One shooter genre video game had AI non-player characters (NPCs) and they had it set up so that they learned from the players, and the NPCs had one give covering fire and shoot at the player/s while the others walked around the side of the area and came to where they could shoot the player from the side, and no players noticed that happened and thought the game cheated and spawned those enemies over there so they complained. Players then used a strategy of going into a small hallway so the NPCs had no choice but to run into the small hallway so then players complained that the AI was dumb because it just ran into its death. The devs tried different strategies like making the NPCs call out what they were doing like "covering fire" etc but people didn't pay attention to that and ultimately because nothing worked they removed all the learning ability from the NPCs and just programmed them with dumber pre-programmed behaviours with no learning involved. It's interesting how these things go sometimes.

Honestly, based on what I've seen so far, I think we are going to see AI being used alongside human creativity as opposed to outright replacing it. Maybe I should let the AI I am creating though also have another version that is trained on my posts so far and see how it goes at writing a Steemit post. It probably won't do too well given I don't have very homogeneous content and it probably isn't really enough data for this sort of thing but it might be interesting to see how it does.
