Anyone who could open a port free of longshoreman unions (aka able to automate) would be a step function above what we have. That's not easy to swing politically though.
Eh. I've worked at a massively automated container terminal free from unions (not in the US). It's not any faster than your US terminals. Less people, sure, but not any faster.
I think you massively overestimate the gains automation would bring you.
Yeah, it’s weird. I was watching a YouTube that showed how Amazon was building their own extra long containers and bringing them up the river in Houston on specially constructed container ships with integrated cranes for unloading/loading.
