If we are able to define what kind of tasks AI will be good at then retrospectively we will be able to come up with what tasks AI is not good at. So what is AI good at? AI is most certainly good at coming up with solutions where the outcome of the task is clearly defined, which is why AI is not going to replace researchers. Research at it's very core does not have the outcome clearly stated, thus the process is more important than the outcome, making it very hard to automate.
A lot of people say coders, marketers, editors will be replaced but I think these will kind of become a single layer of identity, these people's jobs will converge into obtaining a specific outcome by breaking them into smaller chunks of outcomes. it will still take immense creativity (perhaps more, as lot more is being expected from the same person), thus these chunks of outcomes will be largely be done with the help of AI.
So much hype around AI. So AI enables the creative, the deep thinkers that are excited about the output more than process. AI will become the process, does not mean you do not have to understand it. You still need it but a larger part will be done by large language models.
