I love you guys. I really do. But as a privileged American, if I'm just stacking and hodling, for many years into the future, mostly for my kids and grandkids, do I really need a hardware signing device? When the time comes, they just need a few bits of information: my seed words and default derivation paths (though I do have one significant stack with a well-documented with account = 1 not 0). Or am I forgetting something? Hardware device subject to fire, theft, bad random number generator, bit rot, solar flare, supply chain creepiness?
