What is scary is not that Disney (and all the other big companies) are investigating AI as a useful tool, but their first immediate thought is how can we use this to cut even more jobs out rather than how can we use AI as a tool to make our content even better? Everyone seems to believe generative AI is something that will replace human workers, but from what I've seen from folks tinkering with it here, it's just another range of techniques that can be used to do things.
Just like 3D printers are not putting sculptors and set designers out of business, generative AI is not going to put artists out of business, rather will give them another tool with which to make cooler stuff faster.
The problem, I think, is not the existence and development of AI, but the desperation with which large companies are driven to reduce costs and increase profits. It's not AI everyone is scared of, it's capitalism. And capitalism has been capitalizing for centuries now, while we've known exactly what it is.
