> Another is that it changes the way you think about IP addresses, with endpoints getting a /64 instead of a single address like you did in IPv4.

End points get /128, it's just that subnets are now /64.

That simply means that endpoints can auto-assign themselves a new /128 because--instead ofhaving only space for 2^8 hosts in the typical /24 subnet of IPv4--there is now space for 2^64 hosts, which makes it unlikely that collisions will occur.
