I don't see the imminent main threat for professionals to be honest. Even today, the worth of a professionals work (be it artist or developer) is not the ability to look up how to do something specific or to churn out good looking, but random results, but to create results that are coherent on a long-term and and fit into the customers needs.

Example: AI can now generate great single concept arts, but in my opinion it will still take some time until it can do it coherently for a full project where everything needs to fit together. In the same manner the developer needs to write code that fits into existing systems. Both can of course profit already from AI today, but they are not to be replaced as easily.

The way bigger threat lies in all the social aspects of the internet. It's hard already to weed out all the crap when I want to find something specific e.g. on Youtube. I imagine it will be even harder when I need to filter through the low-quality generated content that will be uploaded just for the numbers. Also I see non-curated online discussion platforms and comment sections dying: How am I supposed to properly discuss when everytime I take a stance there will be instantly 10 bots screaming back at me?
