Not totally sure DNSSEC was ready enough to be deployed technically 15 years ago by many people and some improvements have been made since then but not enough to make deployment at all easy. Another factor holding back deployment is the Esperanto problem. Great language, but too few people speak it to make it worth learning. The application that will probably need to go to DNSSEC first is probably money - banks are likely to adopt DNSSEC themselves and then force e-commerce sites to use it next because the losses from phishers routinely compromising ordinary DNS become too great.

Once enough ISPs support DNSSEC for their customers, your bank won't let you make on-line payments or do online banking from ISP connections that don't.
