One of the things that comes up again and again is that AI might help with new ideas on an individual level (by creating access to previously unknown areas of knowledge), but reduces creativity on a collective level because it helps everyone in the same way. I posted about this recently.
This is a bit like Wikipedia being a great place to start research, because one gets easy access to new information, but a terrible place to end it, because the very nature of an encyclopedia means that the information is limited and flattened.
I don't want to debate here the merits of AI on an individual level. The point I want to make is that there are different effects on different levels, and our individualistic culture makes it very difficult to see collective effects when they are very different from individual effects.
@randomwalker and @sayashk make this point (and many others) about science.
