Containerization? That's really interesting. I knew it had a big effect on how shipping worked, but didn't realise it was as important driver of change to the world economy as electrification.

My Dad used to work as a merchant seaman, I believe he got up to first officer and had passed his captain's exam.

But then the big container ships came along, and they needed a tiny fraction of the captains, officers and seaman they needed previously per tonne and he ended up coming ashore to pursue a different career. His stories from those times are pretty amazing.
