"Many of the jobs most at risk are lower down the ladder (logistics, haulage), whereas the skills that are least vulnerable to automation (creativity, managerial expertise) tend to be higher up"

Your job vulnerability, I think, is not only a matter of automation. It also a question of "commoditization". If you become a commodity, meaning that, if * what you do can be well described * your workflow can be well described * the tools you use are becoming standard * there is no real barrier for entering your field. Then, you'll lose very quickly any bargaining power and your 'salary' or 'margin' will decrease.

Technology, as it progresses, tends to commoditize 'producers', whereas usually 'distributors' are less vulnerable.
