This will either be most of them—in which case it is prudent to distill productive activities to a very small list not unlike the one you write above—or it will be a more workable subset. Either way, much of copywriting, rudimentary coding activities for basic websites, etc. are likely to disappear, and one should either become an expert in a very specific type of these things, or avoid them; there won’t be much economic advantage for someone whose body of work is the corpus for GPT-4, etc.!
