Gert B Buttgenbach, one of ECDIS early designers, has some things to say about the state of the art today! And he may have a point - see the post below regarding a grounding due to the crew's mishandling of their ECDIS equipment (click ECDIS Knowledge Deficient in the Categories list on the right side of the page).

Interesting, and based on some things I've heard from friends who use ECDIS, possibly right on target. Safety has to be more than technology - it has to involve the human element, too. Good article, and a good blog, too!
