as a salesperson, I can confidently say that the change will be on the buyer side that eliminates the need for most salespeople. salespeople are already getting less and less time with prospects. Studies show salespeople only influence about 5% of the buying process. What comes next is automating recommendations for software products based on specific needs, buying criteria, etc.

Politicians have been automated through a combination of polling data and lobbyist checks since B. Clinton.

I think sex workers are up there too. Similarly to a good salesperson, the skill and human touch will probably always be a differentiator compared to a machine/AI, leaving at least a niche market for humans.
