It sounds like they're mainly saying that there are certain categories of work in which people use AI to handle things themselves (directly via ChatGPT) and other categories for which they still post a freelance listing (especially if it requires skills across multiple domains).

Writing, illustration, and tech support seem to be the categories people handle themselves most often via AI, according to the first graphic... But then the second graphic suggests that the number of freelance postings for a top 'do-it-yourself-with-AI' category like writing is only down about 0.5% year over year. That almost suggests there isn't really an effect. Even the largest-changing category in that graphic, web development, is down only about 2%.

I think I conceptually can agree with their implication that AI allows freelancers to take on more breadth on their own, but the data/graphics they're presenting are confusing me. I'm not sure I get it.
