I agree that AI does not replace the best people in those roles. It can do an average to good job. Maybe it can reach top 40% of the industry? If you need the best UI or best marketing, humans are still netter. Those top human jobs won't go away for a while.
With that in mind, if you just need average to good, AI can do a good job at a tiny fraction of the cost. So the average to good roles will start getting replaced.
As examples, the sites tellmel.ai, and rivalsee.com for example were created without needing a UI or frontend designer. In the past I would have needed to hire a UI employee or consultant to do either of those at a very large expense (especially for the really good ones).
