Other ships, who can say. But if you are at about 60 degrees south of the equator and keep going due west (or east, of course) you can keep going forever without ever hitting land. You'll pass just below the southernmost point of Chile and just above the nothernmost parts of Antartica.

I wasn't sure if there literally wasn't a great circle route that didn't include land in it. I am moderately surprised to find out there isn't[0]. But I would be more surprised if there wasn't some line of latitude you could follow around antartica that never hits land.

There’s a quote attributed to adam smith “there’s a lot of ruin in a nation”.

A large enterprise such as Google, GE, or IBM can be poorly managed for decades before being economically forced to change.

I observed a team making 25 MM per engineer in a large company that made one change per year. There are products at google that require 400+ pages of documentation/proof to change.
