I should clarify that by "most use cases" I'm not envisioning a bunch of
cryptogeeks [us, or at least myself and a few of us] happily buying up hard
disks, waiting hours, days, weeks to spawn up new full nodes. I'm
envisioning a world where every person has access to this technology and
finds it practical, convenient, and safe ti use.
