Bangladesh is a very populous country that lies almost entirely at sea level, and the Ganga and Brahmaputra flood at least once a year. The problem isn’t not being able to swim in calm water. The best swimmer in the world would still die if he got caught in one of those currents.

At the application level? Yes. At the OS / package level? It’s still a work in progress. And you need the latter to use the former.

Fair, but it means devs will write software that can one day run on open hardware.
