It's clear that AI will be used in this way, but it's much more likely that it will be used for cheating than for automating processes.
I think it can be used ethically to compare odds or make calculations that must first be used by humans, so it can be a great thing.
I'm not sure that AI can really be effectively used for cheating. It doesn’t offer any truly practical advice in areas like investing, trading, or gambling. The financial information it provides is often outdated. You have to drag things out of it and ask leading questions that end up determining its own responses.
Maybe someday there will be a version of AI capable of actual cheating — but I doubt it will be publicly accessible.
