Who thought it was a good idea to have Google just randomly drop words I searched for so I must put double quotes around words so that Google actually searched for them? This is an incomprehensibly stupid thing for a search engine to do.
The fundamental mistake was not making IPv6 backwards compatible with IPv4. You can't just migrate to IPv6, you need to run dual stack which means twice as much work a lot more complexity. I'm 40 and don't expect to ever be able to not need an IPv4 IP to browse the Internet.
