It's not incredibly stupid, because making it backwards compatible is impossible. How could IPv4 devices ever use IPv6 addresses? They simply don't have enough space to store the bits in the address.

Yep, you can't make a 32 bit number contain the same amount of information as a 128 but number. You have to use NAT64 to have the two things talk to each other.
