That only works if you pass around an ugly IP(v6) address. DNS is still a thing, because humans didn't like passing around pure IPv4 addresses, IPv6 addresses are even less human-readable.

Can you please learn how basic networking works before posting on the topic of IPv6?

This comment is suggesting that dynamic DNS companies would go under because of IPv6, which is absurd.
Can you please learn how to read before jumping to conclusions? It's fairly easy, I promise.

After all seems like most end user use of the cloud could be replaced by a raspberry Pi. Things like file sharing via dropbox, webcams/security cams, photo sharing/browsing, internet enabled door locks and garage doors, and monitoring temperatures, furnace, AC, solar, power use,
Sure it's a bit of work, but I suspect many would happily run things themselves if there was a community solution that did it well. Last thing anyone wants to do is replace their smarthone because a random vendor died, lost interest, or was purchased. Like say google killing off Revolv after they bought Nest. Not to mention paying even a few $ a month for an internet enabled lock is silly.
