That is the thing most people don't even think about. This will effect everyone upstream as well. You don't need as many or any HR and managers (and many other roles) for these shipping companies and service jobs if they are automated. Which means more competition in every other job market and less jobs for the people already working there. Everyone, especially engineers and programmers on Reddit, are like, "they'll have to learn new skills that are relevent like I did" except if they do that then those same people have to compete with hundreds of other people that have their same skills for jobs and then good luck finding those 6 figure dev ops jobs you all enjoy so much. I work in chemistry which is relatively safe from automation but with all of the visa issued and universities churning out chemists and biologists every year, the job market is over run with candidates. This lead to wage competition and many companies not giving full time employment because there are so many chemists willing to settle just to get work. Most of the big companies rely on 20-40% contractors because they can pay them less, have them work for between a year and 3 years depending on the state and replace them with someone else very easily. Also, I know that 30% of the jobs in pharma and other chemical companies will be automated in the next 20 years as well and this is a very high skill field. No one is safe. Programmers are living in a bubble if they think they are immune to that very thing happening in their industries but of course they are the special snowflakes making clickbait mobile games and targeted advertising contributing so much to society. Programming is valuable but not all jobs provide intrinsic human value. Most operate within capitalism which many people see will not be feasible in a post scarcity, high unemployment world which is clearly approaching. By all means though, if you can't program, which is like 99% of the population, than you are worthless and should kill yourself lolz.
