They will if they seek to master their tools, both to help them identify subtext in agent responses, and to help them modulate their own responses to achieve the desired outcome. As it currently stands, most engineers I've interacted with don't have these skills down. This subtle latent space is where prompt engineering is moving towards, as RL has created models capable of increasingly sophisticated long-horizon tasks with much less hand holding.
Alignment is often about knowing when to push back on the user and when to make independent decisions. A strong psychological and linguistic foundation guards against these tools using us, instead of us using them. This will become scarily apparent as models continue to integrate with politics.
What I meant by "will they?" was "will they any more than a human already needs to in order to understand other humans?"
I don't think this is legibly that different from human behavior, so if new graduates didn't need those things now why would they need them later (or vice versa).
