I hope passkeys are the same as the USB-C rollout. The internet whines and complains for a few years about their theoretical device from 1999 that won't work anymore and then everything is just plain better for years to come.
So many words spent on HN articles complaining about USB-C or praising Lightning... fast forward a few years to now and I legitimately just pack one cable in my bag and charge any device I happen to bring with me.
