Getting results faster is one way. AIs beat me in speed.
Getting results cheaper is another way. AI is cheaper than I am.
Knowledge across many fields is better. AI beats me here too.
Getting better results in one narrow field is another way, but only one of many ways. I love evaluations of human produced work vs. machine produced work. If we had quality evaluations (not the type-oh riddled garbage most people use.) If we compared AIs to people who work in those fields in occupations recognized by the US Dept of Labor. If we asked both sides to justify their answers. If we had statistically significant sample sizes. Then maybe we could get some good results on quality of work. I can imagine the US DOL spending billions if dollars benchmarking AIs against humans i all the occupations the recognize. Alternately, this could be a very profitable company.
