Which of the following domains will be least impacted by AI? - in terms of job opportunities

People thinking sales will not be affected as much-a lot of sales activity is being automated. All the lead sourcing, initial mail, campaign, meeting, bookings, and everything else up to the closing moment is being automated by AI. Where a lead sales guy +2 lower level folks were required to do. The job is now replaced by AI plus senior guy.

I don't think its about impact anymore. Every field will see some changes, and unless we ourselves adapt to ai and upskill ourselves, we will be replaced eventually by someone who is twice as efficient as us to do the job of 2.
And well the software engineering roles where you even need to do RND and make POC's first, those might still have some elbow room.
