In the case of climate change and being a profit seeking business, I’d assume attempt to identify things whose demand will increase, like land in the areas predicted to remain most comfortable to live, farmland in areas least likely to lose productivity, companies that produce things like water desalination infrastructure, etc, and buy those things early before they become more expensive.
Even there though, what is the actual point of a phone app controlled smart toilet, even if you open sourced the whole thing? Unlocking one’s phone and tapping the app icon, and then presumably a button on the app, is going to take more time than one press of a lever that one is right next to anyway, and the latter doesn’t present as many points of failure.
